: The solid rocket engine is widely used in missile. In order to expand the scope of attack, both iincrease specific impulse and decrease weight are become the research goal. In this paper, we take the vessel of solid rocket engine as research object, simulate the pressure of hydrostatic test, establish the finite element model of solid rocket engine vessel, solve the stress for any element in solid rocket engine vessel and find the maximum stress point by ANASYS, and then we solve reliability by the method of random analysis. According to this reliability, change the pressure which load on the inside of solid rocket engine vessel while insure reliability higher than the criticality. In this analysis, we can increase the pressure which loads the solid rocket engine vessel and we achieve the sensitivity of all parameters.

: In order to control the construction deformation of the tunnel under the existing highway, the pavement deformation under the condition of the tunnel section of shield tunnel in Shanghai was calculated. The deformation of the pavement under the condition of the tunnel was calculated, and numerical simulation is carried out with FLAC3D numerical simulation. In view of the original pavement deformation amount and shield construction deformation increment and over the pavement deformation specification maximum allowable value of contrast the single grouting reinforcement, setting pile and grouting combined with the road pile foundation reinforcement of three different reinforcement scheme is determined. Through the numerical simulation analysis to determine the scheme for the optimal solution, after the construction of the comparison of the actual deformation, second scheme on deformation control is better than expected. It is proved that the prediction with high accuracy and this is an important reference for similar projects.

: This research paper investigates the modification of wind loads on a tall building (principal building) having rectangular cross-sectional shape due to the variation in height of two closely located interfering buildings having a similar plan shape. The models of the three buildings (principal and interfering buildings) are placed in a U shape plan for the study. The heights of interfering building models are varied in two different manners: (1). Height of both the interfering building models is reduced simultaneously (2). Height of only one of the interfering building model is reduced. Wind tunnel experiments are undertaken using five component force balance load cell and the results are reported in the form of X-Y plots. The interference effect causes increase in the torsional moment as height difference of the two interfering buildings increase, also shielding effect causes reduction in the along wind force as height of the interfering buildings increases. Value of torsion on the principal building is observed to be as high as 33 times of that in the isolated case. However, a reduction is high as 69 percent is observed in the force in along wind direction due to shielding.

: Local scour around bridge pier is the main reason for failure of a hydraulic structure like as bridge piers, abutment etc. Local scour around a bridge pier is largely depending on the shape of the bridge pier and how the design is fashionable from the view of construction. Local scour is a complex phenomenon which depends on the discharge, depth of flow, geometry of the pier and type of sediment particle. In this study, geometry i.e. shape of the pier is the main concern. Research is carried out by considering three different geometry pier of rectangular, circular and oblong shape to conclude the optimal shape of the pier at a different flow velocity of 0.146m/s, 0.231 m/s & 0.323 m/s on 15m hydraulic flume under clear water condition using natural sand as the bed material in the university laboratory. Results show an idea that the scouring at the upstream face is directly proportional to the exposed upstream nose area of the pier. It is also shows that the scouring is highest in all cases for the rectangular pier and minimum for the oblong pier.

Soil is a major reservoir for contaminants as it possesses an ability to bind various chemicals. Pollution with toxic heavy metals is a serious concern because once these heavy metals enter the soil they can persist for a long time. In present investigation, the basic soil characteristics of three different soil samples are studied to understand the transport of heavy metal Copper through vertical diffusion and their by plotting breakthrough curves at different depths. The results indicate that the diffusion of Copper at different depths of soil columns is time dependent and increases with the depth of soils. The results of the study are highly useful in designing of the abatement techniques adopted for removal of containments or impurities especially focusing on inorganic pollutants, managing effluent disposals producing from industries processing heavy metals, prediction of heavy metal movement in soils and finally their way to groundwater.

: Presence of moisture on road surface can result in loss of bond between aggregate and bitumen mix due to which stripping can take place leading to reduction in pavement life. Most of the studies all over the world conclude that stripping is mainly caused due to the presence of moisture on the pavement. In this paper the results of a laboratory study that considered increased immersion time of bituminous mix in water along with the effect of moving traffic on the road have been presented on aggregate from three different sources using two bitumen grades. It is found that stripping value is affected by source of aggregate and bitumen grade. Also, it is observed that increase in immersion time and application of traffic pressure affects the stripping value. The pH value of water in which aggregates were immersed was also varied. The increase in alkalinity of water was found to increase the stripping of aggregate.
