不同加载面下隧道地震响应数值模拟

Numerical Simulation on the Tunnel Earthquake Response of Different Loading Surfaces

研究隧道在不同加载面下加载地震波时的地震响应情况,具有重要的工程意义。本文针对不同地震波、不同加载面下隧道的地震响应情况进行数值模拟计算,分析两者之间的差异,得出不同加载面情况下计算结果差别较大,隧道地震响应规律不尽相同。因而对不同的工况应采用不同的加载方法。

Analysis on the tunnel earthquake response of different loading surfaces is very useful for engineering . This paper discussed the tunnel earthquake response of different earthquake wave and different loading surfaces with numerical simulation method,anlysed the difference of them.In the end this paper got the conclusion was that the calculation results of different loading surfaces existed large disparities,and the law of the tunnel earthquake response is also different .So for different condition people should choose different loading method .
