In order to study the dynamic responses of long-span suspension bridge with CFRP cables, a suspension bridge with CFRP cables which span of 896m is designed. The dynamic responses of suspension bridge with steel cables and CFRP cables are analyzed by ANSYS software, the effects of structural design parameters...

Based on ANSYS finite element analysis software, the finite element numerical analysis model of the medium pressure vertical pipe was established. The seismic response of pipeline was analyzed by using the structural transient dynamic analysis, which provides a theoretical basis for the seismic design...

An analytical method of SRF considering MDOF effect of bridge structure was put forward. The definition and calculation method of amplification coefficient were proposed. Calculation programs were compiled to analyze various equivalent pier MDOF model of bridge through the combination of finite element...

Variable weight synthesis method is a safety assessment method which is using the varied weight principle, base on analytic Hierarchy Process and combining the theory of Grey relevancy, it reduce influence that secondary cause is not obvious in assessment process, and make the result more correct and...

Location of Nanmenxia Reservoir is very important, and the reservoir has a significant benefit. But the leakage of dam foundation was serious; there was an urgent need to find out leakage location and path. The effect of previous treatment was not obvious, and it is very important to find out the situation...

According to the characteristics during construction of the metro incidents,an emergency capability evaluation index system of metro construction was established in the paper,which based on the relevant theory of the ability of emergency management. Build up a metro construction of emergency capability...

In order to study the effect of pounding at expansion joints of beam bridge on the seismic responses of bridge structure during earthquake the research is based on multi-particle of single degree of freedom system, and the pounding effects of adjacent girders on seismic responses with 3 different of...

The interaction analysis and evaluation on tunnel passing through underlying vacant areas is essential in highway construction. A 3D numerical model of tunnel at underlying vacant area has been established to analysis the deformation and mechanical characteristic of tunnel structures. According to the...

As a new type of underground engineering reinforcement technology, the pipe-roof method has shown its significant superiority in shallow buried large section tunnel engineering in high traffic urban areas. According to the two design scheme of pipe-roof engineering, the 2-D numerical analysis model has...

With the development of urban economy, highway passenger transport hubs as the internal and external communication bridge between cities, become more and more important. The traffic organization directly impacts the efficiency of the hub. This paper analysed the present situation of traffic organization...

The development and utilization of urban underground space is an effective way to use the limited space more reasonably and economically which has great practical significance for expanding the urban space capacity and improving the quality of the city. This paper explores planning idea, overall layout,...

A database of 30 deep excavations of field monitoring on Nanjing subway stations is presented and discussed. In order to reflect the differences of settlement in different area around the excavation, monitoring points were arranged at three areas: the position 1/4 and 1/2 long side, or the long side...

This paper studied on the fatigue experiment of two CRTSIII slab ballastless tracks on subgrade under high-speed train load, one was the track structure with self-compacting concrete thickness of 70 mm (the 70 mm's), the other was 90 mm (the 90 mm's). The two tracks were made of 1:1 full-scale test models...
