摘要
简要分析了位于巨厚冲积层表土下,竖井破坏的特点及力学机理。根据井筒破坏的力学机理,设计制定了预防和加固竖井破坏的技术方案卸压套壁法,并通过其一工程施工实例说明该方案的施工特点、效果及适用情况。
The characteristic and mechanical mechanism of shaft failure under mega-thick alluvial surface layer are briefly analysed. Based on the mechanical mechanism of shaft failure, the pressure release and casing-wall method is applied to draw up the technical project to reinforce shaft and prevent it from failure. The construction characteristic, result and its practical value are presented in the light of an example of engineering.
