摘要
应力波与隧道衬砌的相互作用问题为岩石力学的一个十分复杂的问题,到目前为止还没有得到圆满的解决。对于考虑介质与结构弹塑性性质的课题,解析解更难以求得。研究表明长波与深地下硐室的作用问题可以用拟静法解答。本文用拟静法研究了考虑岩体塑性性质时长纵波与地下硐室的相互作用问题。并获得了确定长应力波对于隧道支护作用的解析解。
The interaction of stress wave with tunnel structures in rock mass is a complex problem, which up to now has not been solved completely. The problem becomes more sophisticated when elasto-plastic properties of rock mass and structures are considered. Some researches are shown that the problem of interaction between long stress wave and tunnel structures can be solved by pseudo-static method. In this paper the interaction problem between long longitudinal stress wave and tunnel structures with considering the plasticity of rock mass is studied by pseudostatic method. Analytic solution of the effet of long longitudinal stress wave on the lining of tunnel is obtained.
