摘　　要：基坑支护是基坑工程施工极为关键的环节,基坑支护技术的选择一定要合理、科学,而施工质量也要严格控制。结合曹县人民医院医技综合楼深基坑工程,通过对工程场周边环境及工程条件进行了具体的分析,采用钻孔灌注桩与旋喷桩的支护方案,并对钻孔灌注桩与旋喷桩的施工质量控制进行探讨,取得较好支护效果。Foundation pit support is an extremely critical link in foundation pit engineering construction,the selection of foundation pit support technology must be reasonable and scientific,and the construction quality must be strictly controlled.Based on the deep foundation pit project of the medical technology complex building of caojun county people’s hospital,this paper analyzes the surrounding environment and engineering conditions of the project field,adopts the support scheme of bored pile and rotary grouting pile,and probes into the construction quality control of bored pile and rotary grouting pile.

关 键 词：深基坑 支护 钻孔灌注桩 旋喷桩 施工技术
