以某深基坑工程为例,为保证基坑施工正常进行,并且不对周边原有建筑物及地下市政设施等产生过大影响,同时满足安全、经济及合理的要求,在支护方案选型上,重点考虑基坑的变形控制,最终采用了桩锚-支撑联合支护方案。实施结果和监测数据表明,该支护方案达到了预期的支护效果,对基坑的变形控制,满足安全、经济和工期要求。
以某深基坑工程為例,為保證基坑施工正常進行,併且不對週邊原有建築物及地下市政設施等產生過大影響,同時滿足安全、經濟及閤理的要求,在支護方案選型上,重點攷慮基坑的變形控製,最終採用瞭樁錨-支撐聯閤支護方案。實施結果和鑑測數據錶明,該支護方案達到瞭預期的支護效果,對基坑的變形控製,滿足安全、經濟和工期要求。

This paper introduces a retaining project of deep foundation pit.The deep excavation on support scheme selection puts a strong focus on its deformation control in order to ensure the normal construction,has no impacts on crude oil surrounding buildings and underground municipal facilities and meets the security,economic and rational principles at the same time,eventually the combined method of pile-anchor and internal brace was adopted.The results of implementation and the monitoring data indicate that the program has achieved the desired support results;it＇s very good distortion control to meet the safety,economic and schedule requirements.It can provide useful reference for the similar projects.
