高层建筑深基坑支护施工技术分析

Analysis on Construction Technology for Deep Foundation Pit Support in High-rise Buildings

高层建筑深基坑施工难度大,为保证深基坑支护效果,文章从排桩支护、地下连续墙支护、土钉墙支护和锚索支护4个方面阐述了深基坑支护施工技术要点,立足深基坑支护现场施工期间常见问题,阐明施工内容,包括降排水施工、基坑监测和编制特殊施工方案,旨在构建标准化深基坑支护施工体系,为现场作业提供明确的技术指导。

The construction of deep foundation pit in highrise building is difficult.In order to ensure the supporting effect of deep foundation pit,this paper expounds the key points of deep foundation pit support construction technology from four aspects of row pile support,underground continuous wall support,soil nailing wall support and anchor cable support.Based on common problems during the onsite construction of deep foundation pit support,this paper expounds the construction content,including dewatering and drainage construction,foundation pit monitoring and special construction scheme compilation.The aim is to construct a standardized construction system for deep foundation pit support and provide clear technical guidance for on-site operation.
