特殊情况下深基坑围护测斜及变形浅析

Deep excavation retaining structure lateral deformation under the unusual circumstance and deformation analysis

结合工程实例具体阐述当测斜管不能正常使用情况下运用全站仪代替测斜仪进行深基坑围护结构的倾斜测量,同时运用岩土工程相关知识对所得监测数据表现的变形及突变原因作了深入分析,获得了预期的安全监测成果,确保了深基坑工程的顺利实施。为今后类似情况的处理提供借鉴。

Deep excavation retaining structure＇ s lateral deformation using total station instead of inclinometer was expatiated associated with an actual project when lateral pipe cannot work normally. Meanwhile, according to geotechnical engineering knowledge, a detailed analysis on deformation and jump was performed, and prospective safety supervision outcome was obtained, which assure the implementation of deep excavation engineering and offer a reference to some similar projects.
