摘　　要：随着城市建设进程的进一步加快,地下空间作为城市的重要空间资源,其基坑施工对安全质量的要求也在不断提高。为确保地下空间施工整体质量及其安全,选用合理的施工方法有着重要意义。盖挖逆作法因其适用性高及控制土体变形能力强,被广泛应用于地下空间施工中。以某地下商业街工程为研究对象,对施工中的潜在风险进行探讨,对盖挖逆作法的施工技术要点进行提炼,同时基于现场监测结果证实了其在地下空间应用的有效性。With the further acceleration of the process of urban construction,the underground space as an important space resource of the city,its pit construction requirements for safety and quality are also constantly improving.In order to ensure the overall quality and safety of underground space construction,it is important to select reasonable construction methods.Because of its high applicability and strong ability to control soil deformation,the inversion method of cover excavation is widely used in underground space construction.Based on an underground commercial street project as the research object,this paper discusses the potential risks in construction,refines the key points of construction technology of reverse excavation method,and verifies the effectiveness of its application in underground space based on field monitoring results.
