With the development of China's shipping industry, the maritime cargo transportation industry chain is becoming more and more complete, resulting in more and more problems. Among them, the transportation of dangerous goods by waterway is also receiving more and more attention. As an important method of transporting dangerous goods, the safety of waterway transportation is particularly important. In order to ensure the safety of waterway dangerous goods transportation, it is necessary to establish a scientific and reasonable safety evaluation index system, and conduct a comprehensive and systematic safety evaluation of waterway dangerous goods transportation. Firstly, this paper takes the transportation of dangerous goods by waterway in Weihai City as an example, and selects five primary evaluation indicators, including environment, personnel, ships, goods, and management, as well as their secondary and tertiary evaluation indicators, based on the actual situation; secondly, a safety index system for the transportation of dangerous goods by water in Weihai City has been constructed, and an example analysis has been conducted on it; finally, safety management measures for the transportation of dangerous goods by waterway in Weihai City were proposed.

This paper investigates the distribution characteristics of earth pressure on circular caisson foundations in soft soil areas based on practical engineering considerations. Utilizing a three-dimensional numerical analysis model and a displacement-based method for earth pressure calculation, the lateral earth pressure on the retaining structure is examined. Adjustments are made to the distribution pattern of earth pressure on circular caisson foundations in soft soil areas. The study demonstrates that the radius of the caisson significantly influences the spatial distribution of soil pressure. Additionally, empirical formulas for the depth and radius of the reduction in soil pressure around circular caisson foundations are obtained through the research. Comparative analysis reveals that the modified earth pressure planar foundation beam method, which accounts for the arching effect, is simpler, features more mature parameter selection, and is more cost-effective than the three-dimensional finite element method. In comparison to the standard planar elastic foundation beam method for earth pressure, it aligns more closely with the actual direction of displacement.

Earthquake is a kind of common and terrible sudden natural disaster. Frequent earthquake disasters bring inestimable loss of people and property to human society. Based on the earthquake background and considering the impact of aftershocks on emergency rescue activities, this paper constructs a multi-objective vehicle routing optimization model with the objectives of time, risk, fairness of material distribution and minimum cost. Through simulation examples, conclusions are drawn: Decision makers should first consider risk and time, when considering time, focus on considering the time window to meet the fairness of material distribution, and finally consider the cost.

To achieve semantic segmentation tasks in practical applications such as autonomous driving, networks need to efficiently process high-resolution images while maintaining high accuracy. This requires methods to effectively fuse spatial information in high-resolution images with semantic information in low-resolution images. To address this, this paper proposes a Multi-scale Fusion Convolutional Network (MFCNet) based on a single-branch network structure. In order to simultaneously handle information at different scales and assist the network in capturing a wide range of contextual information, separable Multi-Scale Convolution Modules (MSCM) are introduced to enable the network to obtain richer and more comprehensive feature representations. Additionally, considering that shallow-level information is difficult to directly restore resolution, a Dual-Attention Fusion Module (DAFM) is designed, introducing two attention mechanisms to respectively weight feature maps at different resolutions. Experimental results demonstrate that MFCNet achieves outstanding performance in real-time semantic segmentation tasks.

Reading is an important part of English teaching. Traditional English teaching has always on the basis of teaching new words, grammar and long and difficult sentences, however, it is necessary for us to carry out the reform and innovation of English teaching in order to change the ineffective way of English teaching. In this paper, three schema forms of schema theory are introduced into high school English reading teaching activities. It is hoped that schema theory can help students overcome difficulties in learning, improve the quality and speed of reading, stimulate their interest in learning, change the way from passive learning to active learning, and find a way in using schema to better help senior high school students improve their reading abilities.

This paper introduces the ternary composite drive technology and the characteristics of the technology. The characteristics of ternary composite flooding produced water were sorted out, and the characteristics of complex organic composition, poor biochemical treatment, high oil content, high suspended solids content, high viscosity and high emulsification degree were sorted out. Three ternary composite flooding produced water treatment processes were introduced. Under the condition of ensuring that the effluent meets the requirements of reinjection water, the advantages and disadvantages of the three processes are compared, and finally the third process flow is determined to be the optimal option. The process can not only effectively improve the treatment effect of ternary composite flooding produced water, but also overcome the shortcomings in the conventional process, improve the feasibility of the process and reduce the cost.
