摘要/Abstract

摘要： 通过数值分析和模型试验研究，揭示了竖向可缩性井壁附加力分布规律。研究表明，可缩性井壁可有效衰减附加力和井壁截面轴向应力；与单一可缩接头相比，设置两个可缩接头衰减附加力更为有效；提出的可缩接头设置优化原则，对科学、合理地设计竖向可缩性井壁具有重要的指导意义。

Abstract: The distributing rule of additional forces of compressible shaft wall is given by numerical analysis and model test. It is shown that the compressible shaft wall can reduce the additional force and the section axial stress of shaft wall effectively; Compared to the single compressible tie-in, two compressible tie-ins setting is more effective. The setting optimization principle of compressible tie-in is brought forward; and it has important guidance meaning to design compressible shaft wall reasonably.

Key words: settlement stratum, compressible shaft wall, additional force
