某深基坑支护工程实例分析

A Case Study of Support Project for Deep Pit

以实际深基坑支护工程为列,该基坑工程的支护形式有双排桩结合深层搅拌桩,深层搅拌桩结合灌注桩等,分析了现场监测资料如基坑变形、桩体变形以及对周围建筑物的影响等。结果表明,基坑计桩体变形均控制在12 mm之内,周围建筑物变形控制在6 mm之内,说明此次基坑支护结构设计是成功的,能够确保基坑及周围建筑的稳定。

An actual deep pit works was taken le-row piles combined with deep mixing piles, for the column, the pit engineering support with the form of doub- drilling piles combined with deep mixing pile. The field monito- ring data was analyzed, such as pit deformation, deformation of the pile as well as the impact on the surrounding buildings. The results show that the deformation of pile and pit are controlled within 10 mm, surrounding build- ings deformation controlled within 5 ram, indicating that the structural design of the pit is successful, to ensure the stability of pit and surrounding buildings.
