摘　　要：为了揭示双卸压槽修复破裂井壁的机理,采用对比方法,通过设置双卸压槽的井壁试件与未设卸压槽的普通井壁试件的模型试验,对此问题进行了研究。研究结果表明:对于设置双卸压槽的井壁,双卸压槽的压缩变形可有效地衰减井壁附加力,确保井壁安全;对于未设卸压槽的井壁,井壁竖向变形很小,极易破坏。For opening out the mechanism of repairing broken shaft lining by double pressure -release toughs method, in the thesis shaft lining in which is installed double pressure - release toughs and general shaft lining in which is not installed pressure - release toughs are experimental researched. Research result show that, for shaft lining which is installed double pressure - release toughs, compression deformation of pressure - release toughs can effectively attenuate subsidiary load of shaft lining, and shaft lining is safe. However, for general shaft lining in which is not installed pressure - release toughs, it has less vertical deformation, and it can be easi- ly damaged
