摘　　要：大型深基坑支护工程施工中,内支撑体系通常采用混凝土内支撑,但混凝土内支撑存在资源浪费大、工期慢、支护费用高等缺点。通过对某项目混凝土内支撑与钢混支撑相结合的内支撑设计方案比选及钢混支撑相结合的内支撑施工技术应用分析,阐明钢混结合内支撑在深基坑支护工程发挥的重要作用及优点,以期为相关深基坑支护工程施工提供参考。In the construction of large-scale deep foundation pit support engineering,the internal support system usually adopts the concrete internal support system,but the concrete internal support has the disadvantages of large waste of resources,slow construction period and high support cost.Based on the comparison and selection of the design scheme of the internal support combined with concrete internal support and the application analysis of the construction technology of the internal support combined with steel concrete support for a certain project,this paper expounds the important role and advantages of the internal support combined with steel concrete support in deep foundation pit support engineering,in order to provide reference for the construction of relevant deep foundation pit support engineering.

关 键 词：深基坑支护 内支撑体系 钢混结合内支撑
