Analysis is conducted on the temporal and spatial variations of stable isotopic composition in precipitation, using the data of IAEA/WMO sampling stations, in Yangtze river basin. The correlations between δ18O in precipitation and air temperature/amount of precipitation are analyzed at individual stations and in the whole valley on monthly or annual scales. There is notable amount effect, the distinct inverse relationship between δ18O and precipitation, on monthly scale in the Yangtze valley and at the selected stations except Chongqing. Compared with monthly scale, the positive correlation between δ18O and air temperature is more marked on annual scale. The interannual variations of δ18O reflect the change of large-scale climate and environment, and are mainly controlled by large-scale weather conditions.

With regard to the design of ultimate vertical bearing capacity of single rock-socketed pile, theoretical formula recommended by “Technical code for building foundations” (JGJ 94-2008)and static loading test are the two most popular methods. But results obtained from this two approaches have great differences. The average of relative difference (note: taking absolute value) is even up to 45.7%, and in most cases the values from the former are greater than that from the latter, as found from analyzing the static loading test data of 101 rock-socketed piles. By using founded GA-BP neural networks which taking 101 rock-socketed piles' static loading test data as a training sample, 10 predicted results have a good agreement with expected values from static loading tests. The average of relative difference is about 5%. GA-BP neural networks can also be used in analyzing the vertical bearing behaviors of rock-socketed pile. Using the GA-BP neural networks as mentioned above, varying the magnitude of ratio of rock-socketed depth to pile diameter, and keeping the rest of other parameters as unchanged constants, a curve of relationship between the variable ratio and output predicted vertical bearing capacity could be achieved, which revealed that for a given construction field and workmanship, a most reasonable value of the ratio could be found which corresponding to the maximum value of ultimate vertical bearing capacity, but no constant value has been found while changing the site condition.

The prestressed concrete covering layer system, different with the general reinforced concrete cover, is a complex system which includes not only the non-uniform layer of concrete, but also the non-prestressed reinforcement, the metal corrugated pipe and the cement paste incrustation body in the pipe. Therefore, the study for carbonization corrosion of the prestressed concrete structures should consider effect of the stress and deactivated film position of reinforcing bar. Taking into consideration of the effect of stress level in concrete diffusion process, the carbonization reaction and diffusion process in the complete carbonated zone and the half-carbonated one under multi factor is analysed. It presents the durability limit state equation for prestressed concrete structures under carbonization condition, which can determine the depth of the covering layer system for prestressed concrete structures.

Traditional steel moment frames use welded beam-column connections, which are susceptible to brittle fracture and commonly have large residual deformation after the earthquakes. A novel beam-to-column connection for steel moment frame is proposed. Four full-scale new connections and two connections without self-centering capacity were tested under cyclic lateral load, the connections' strength property, energy-dissipation capacity, seismic behavior of hysteresis loops as well as angles and posttensioning strands' behavior are investigated. The results show that the connection's prestressing forces determine the connection's self-centering capacity, and angles are important for energy dissipation. Under 5% drift, the columns and beams remain elastic while the angles sustain inelastic deformations. After the loading, the connections have zero deformation. The connection can restore to the original position.

The fulfillment of equity in the distribution of urban public green spaces is a great goal to urban planners, who must identify at least how many public green spaces are required to meet all residents' relaxation demand and where they should be. Since it is commonly accepted that the accessibility is the most important quality of public green spaces for citizens' equal use, in this paper, a planning technique integrates the accessibility evaluation into GAP analysis in a GIS is presented, through which urban planners can analyze the gaps of the requirement of urban public green spaces and their distribution. The Special Economic Zone of Shenzhen in China is used as the experimental site for users to better understand this planning method, and results carried out by this paper demonstrate the power of this approach to identify where should be paid more attention to in the future green space planning and construction.

A cascade biological pretreatment reactor(CBPR) was used to improve the removal rates of ammonia, small molecule organic compounds and microcystins from eutrophic raw water. The pilot-scale installation was run continually based on the conventional water treatment process(CWTP) and the process combined with biological pretreatment(BPTP). The effluents of each reactor were analyzed. The results show that CBPR removes more than 75% of ammonia and helps to increase the DOC removal rate from 30.3% to 49.2% in the coagulation-sedimentation reactor. Compared with CWTP, the removal rates of extracellular microcystin-LR and total microcystin-LR are increased 47.4% and 43.1% in BPTP, respectively. The CBPR removes effectively small particles with diameter less than 5µm and increases big particles with diameter more than 7µm, which enhances the particles removal in coagulation-sedimentation and filtration reactors. The CBPR degrades effectively small molecular organic compounds, decomposes big molecular organic compounds into small ones and promotes the removal of medium molecular organic compounds by CWTP.

Pipe jacking is widely used in the underground construction, but few studies are focused on the pipe wall stability and no specify rule is presented in the codes. According to this situation, theoretical and numerical analysis is applied in research. Through numerical simulation, the inner force and deformation of steel pipe can be obtained, but the control criterion of wall thickness is still in lack. Based on the result of numerical analysis, the deformation of steel pipe is characteristic of arch, so the stability theory of arch in the material mechanics is lead to compute the critical pressure. Comparing the critical pressure with the actual force of steel pipe, the stability of pipe wall can be determined. The steel pipe of intake pipe design of a heat-engine plant is studied as project case, and the stability of pipe wall under different wall thickness is studied using the methods presented. The analysis and optimum design shows that the 22mm can be determined as the proper wall thickness instead of the original design thickness—34mm, and the project cost will be decreased significantly.

The calculation of the pile foundation internal force under horizontal loads always constitutes a fundamental prerequisite to an insight into the pile deformation. Through the sensing fiber embedded in pile shaft, this paper studies the deformation of bored pile under horizontal loads, and deducts the formula of pile deflection and bending moment under horizontal loads by means of BOTDR-based distributed detection. Then through the project case, a comparison is made between the value calculated by the data obtained through the embedded fiber and the value measured by the displacement sensor. And with the analysis of the pile foundation bearing capacity under horizontal loads, the study shows that a reliable basis for pile foundation design can be achieved by the effective detection of such pile deformation as strain, deflection and bending moment, based on the BOTDR distributed fiber sensing technology.
