深圳某深基坑咬合桩新工法及变形分析

New construction method and deformation analysis of a deep foundation pit occurred in Shenzhen

通过对深圳福田区紫元元大厦项目深基坑工程中咬合桩的施工工艺介绍及围护桩体的变形观测分析,对咬合桩的成桩工艺进行了改进,降低了生产成本,总结了围护桩体的变形规律并进一步探讨了深基坑的变形规律。其次,针对工程中出现的问题,结合工程实际提出了解决方案。

Through the introduction of the construction technology of the secant piles and the deformation observation of the retaining piles in the deep foundation pit project of the Ziyuanyuan Mansion, Futian District, Shenzhen, the pile-forming technology of the bite piles is improved and reduced production cost, summarize the deformation rules of retaining pile body and further discuss the deformation law of deep foundation pit. Secondly, in view- of the problems in the project, combined with the actual project proposed solutions.
