【摘要】 本文编制了不均匀侧压下混凝土井壁结构分析的非线性有限元程序，并用它对井壁结构模型进行了计算分析。结果表明，在不均匀侧压下现行设计的冻结井壁中不会出现拉应力和具有很高的承载能力，其计算值与试验图较好地吻合，从而为冻结并用采用混凝上井壁支护提供了设计依据。更多还原

【Abstract】 A finite element program is worked out for the concrete shaftlining under non-homogeneous lateral pressure, it is applied to calculate the concrete shaftlining, the results are presented in the current designing that considerable well bearing capacity is obtained and the tensile stress is eradicated in the frozen shaftlining. The results are well consistent with that from the experiments.更多还原
