塌方是隧道建设当中常见的灾害，这不光对施工工期造成影响，并且会产生经济损失，对整体工程的建设产生影响。采用极限分析上限理论对考虑孔隙水压力作用的深埋矩形隧道塌落曲线方程和塌方范围进行理论推导，并分析了各个参数对塌方形状及塌方尺寸的影响，为实际工程的设计和施工提供参考。

Common disasters of landslides is the tunnel construction,it not only affect the con-struction period and can produce economic losses.The disasters impact on overall project construction. The paper has employed the limit analysis upper bound theorem to investigate scope of the collapse in deep-buried square tunnel under pore water pressure.And the analysis of each parameter’s influence on collapse shape and collapse dimension has been done.The research provides a reference for practical en-gineering design and construction.
