概率积分法预计隧洞开挖过程中岩石位移

In the tunnel excavation blasting, mining and other factors will lead the whole rock stress and structure damaged, produce a part sinking space, which leads to the upper downward displacement of rock. In this paper, overlying strata movement as a random process, thus using stochastic medium theory study of rock movement, using probability integral method for tunnel excavation in rock in the process of displacement are expected, and the combination of a pumped storage power station actual observation data, on the expected parameters inversion, the project has a certain reference value.
