摘　　要：围岩稳定性是地下厂房方案推进的关键因素,也是地下工程的研究热点。本文依托新疆某大型泵站,采用大型非线性有限元软件,对分层开挖方式下地下泵站厂房做了三维弹塑性有限元计算,得出了围岩的应力、变形、塑性分布特性,提出了工程建议。The stability of surrounding rock is the key factor to promote the scheme of underground pump house,and is also a research hotspot of underground engineering.For a large pump station in Xinjiang,three-dimensional elastic-plastic finite element calculation was conducted with large-scale nonlinear finite element software for the underground pump house to be constructed with layered excavation.The stress,deformation and plastic distribution characteristics of surrounding rock were calculated,and engineering suggestions were put forward.
