Reliability assessment method for environmental vibrations of a tunnel embedded in layered foundation
Authors: Xu Yonggang , Guo Huiji , Di Honggui 
Published: May 2021

Abstract
This paper proposes a reliability assessment method for environmental vibrations of a tunnel embedded in layered foundation under moving train load. Based on wave functions transformation, a vehicle-track-tunnel-soil model for evaluating system dynamic response can be established. Then combined with the Monte Carlo simulation, the reliability assessment of environmental vibrations is realized. The effect of soil parameter uncertainty on the prediction result of environmental vibrations is analyzed via case studies. The results show that the predictions from the deterministic model tend to be conservative, which is less than the superior limit of 95% confidence interval of the uncertainty model predicted outcome. The soil parameter uncertainty has less influence on the distribution of system dynamic response, which mainly affects the system dynamic response amplitude.

Published: May 2021

Abstract
Over the stress state of the sliding body artificially assumed in Limit equilibrium method, the real stress state from any numerical analysis can be imported into a limit equilibrium analysis where the normal stress and shear stress are computed with respect to any selected slip surface. Considering the vector characteristics of force and the strength reduction definition, vector sum method by strength reduction technique was proposed, in which the factor of safety (FOS) can be directly calculated by the force and moment equilibrium. Finally, numerical experiments with six possible conditions are used to verify this proposed method, and the results show that the FOS obtained by the proposed method is in good agreement with the average FOS by limit equilibrium methods.

Research on cost management of prefabricated construction based on BIM
Authors: Wen Zhen , Zhang Hanxi 
Published: May 2021

Abstract
In recent years, prefabricated construction has been widely concerned with its significant advantages of high efficiency, environmental protection and energy saving. However, the prefabricated construction in China is in the initial stage, with more theoretical research than practical cases. Even with strong policy support, the development of prefabricated buildings is relatively slow. There are many reasons for this. The main reason is that the cost of prefabricated construction is too high for most developers to bear. This paper attempts to study the effect of BIM Technology on the whole process of cost management, aiming to solve the problem of cost compression in the implementation stage of prefabricated construction project and overcome the bottleneck of prefabricated construction development.

Abstract
As an important part of the world cultural heritage, industrial architectural heritage is an important witness to the achievements of the development process of human industrialized civilization. With the national industrial structure adjustment and urbanization, many typical industrial factories in China are facing the problem of land replacement, among which, the modern industrial architectural heritage is facing the corresponding problem of conservation and reuse. People’s demand for material and cultural life is increasing, and they are more concerned about the protection of urban heritage and memory, which actively promotes the protection of industrial architectural heritage and also puts forward higher requirements for the utilization of industrial architectural heritage. The research in the field of industrial heritage in China started late compared to that in Europe and the United States, and usually, architects dominate the design of industrial heritage reuse more than heritage conservators. This paper addresses the problems in the process of conservation and reuse of industrial architectural heritage, and carries out research work from the perspective of heritage conservation and reuse design. It analyzes the current situation of industrial building heritage reuse design in China and conducts research on the problems existing in the process of industrial building reuse design. It also discusses the bottom line and criteria for the conservation and reuse of industrial building heritage, and discusses the design strategies for the conservation and reuse of modern industrial building heritage according to the industrial building research results in categories.

Abstract
Due to High-Density Polyethylene Pipes (HDPE) hold the characteristics of reliable connectivity and service life, good impact resistance, low fluid resistance and excellent corrosion resistance, especially for large diameter HDPE pipes are more economic, they have been applied to drainage projects. The overlength HDPE pipe with large-diameter has the combined characteristics of rigidity and flexibility, namely, rigidity is dominating within small pile length, flexibility will then dominate with the increasing of pipe length, which lead to onshore launching will be under dynamic changing process, hence the slope of launching ramp, the bearing capacity of the pipeline onshore launching system and the linear control will be very critical, which will make onshore launching of over length HDPE with large diameter more difficult. Based on the numerical dynamic analysis and simulation, and based on the JIGCC Project in Saudi Arabia, the onshore launching process of overlength HDPE with large diameter is studied. The results not only state the loading state of HDPE and launching systems during the onshore launching stage, but also provide a theoretical basis for a more reasonable and economic design of the over length HDPE with large diameter onshore launching system.
