High Speed Railway

Nowadays, railway tunnel construction faces huge developments and opportunities, with a tendency for high speed and long distance. How to effectively apply the information in the construction process has been the focus of current research. According to the Xian-nvyan tunnel in Xicheng high-speed railway, our research was based on the geological forecast, selecting appropriate tunneling model parameters to establish the 3D calculation model. Through the numerical simulation of three tunnel excavation and support methods, we analyzed the displacement of surrounding rock and the plastic failure to select the construction method reasonably. Compared with the actual measured data, we judged the rationality of the selected scheme and model parameters, so as to provide design parameters which conform to the surrounding rock properties for the subsequent construction, thus optimizing the construction program and applying the concept of information-based construction in engineering actually.

Station Structure

Much concern has been paid on the human-induced vibration of high-speed railway station structures in recent years. But the vibration responses are influenced greatly by are two key factors, which are rational pedestrian load model and accurate structure calculation model. Field test, therefore, is the most directly and valuable method to obtain the vibration responses of large-span railway station structure. The vibration responses of the waiting floor of the Hangzhou East Railway Station, which is just completed, are measured and analyzed. The test results showed that the vibration of waiting room floor under pedestrian load cannot be neglected for vibration comfort evaluation.
