| 摘 要： | 通过现场监测的方法,对沈阳某超深基坑的支护设计进行了研究.结果表明:该超深基坑采用桩锚支护方案,总体可行,但支护结构变形过大,安全储备不足,类似工程应采取相应措施来提高支护设计的安全性;附近地铁隧道开挖,对基坑稳定影响很小,支护设计可不予考虑;地基土冻胀对该基坑稳定性的影响不可忽略,是沈阳越冬基坑工程所要考虑的一个因素.研究结果为沈阳地区的超深基坑工程设计和施工提供了重要参考.

| Abstract: | A lasting in-situ monitoring was done to investigate the design of the supporting system for a very deep foundation pit in Shenyang.The results showed that the design applying an anchor pile system to the foundation pit is feasible on the whole,though the anchor piles are overdeformed somewhat,thus resulting in insufficient safty factors.Taking appropriate measures is therefore necessary to improve the safty of anchor pile supporting system for similar foundation projects.The excavation for a subway tunnel ... |
