摘　　要：基坑支护技术在项目施工阶段扮演着重要角色,伴随地质环境变化,其施工难度也将受到一定影响。在复杂地质条件下,咬合桩施工质量可以决定基坑是否发挥自身实际作用,基于此,以南方科技大学附属医院(校本部)项目为研究对象,通过分析基坑支护技术特点,总结项目施工重难点,针对硬咬合桩施工方法、放坡、插筋、挂网喷锚以及冠梁、连梁支撑体系施工等所应用基坑支护技术进行了详细论述,以降低基坑变形、坍塌等事故发生概率,保证施工安全性。The foundation pit supporting technology plays an important role in the project construction stage.With the change of geological environment,its construction difficulty will be affected to some extent.Under complex geological conditions,the construction quality of the occlusal pile can determine whether the foundation pit can play its actual role.Based on this,the project of the Affiliated Hospital of Southern University of Science and Technology(campus)is taken as the research object,and the key and difficult points of the project construction are summarized by analyzing the technical characteristics of foundation pit support.In order to reduce the probability of accidents such as deformation and collapse of foundation pit and ensure the safety of construction,this paper discusses in detail the construction method occlusal pile,slope release,bar insertion,net spraying anchor and crown beam and beam connecting support system construction.
