摘要
在流变地层中,由于土体力学性能差,导致土体自稳性能差,出现围护桩侵入结构边线的现象,基坑工程中称之为围护桩侵限。围护桩侵限侵占主体结构空间,影响后续主体结构施工。本文以流变地层中某地下室基坑工程为案例,对该基坑工程中围护桩侵限问题进行了分析研究,总结出流变地层中围护桩侵限原因、预防及处理措施,为类似地层条件下基坑工程提供参考。
Because of poor mechanical properties and self-stability of rheological strata,the invasion of retaining pile occurs with foundation pit engineering frequently.The invasion of retaining pile will encroach on main structure space and affect subsequent structure construction.Based on the two-story basement foundation pit project in rheological strata,the invasion of retaining pile has been researched.In the meantime,causes,precautions and countermeasures of invasion of retaining pile have been summarized,which provides a reference for foundation pit engineering under similar strata.
