摘　　要：结合扬子石化清净排口基坑工程,介绍了水泥搅拌桩与土锚组合支护结构的实际应用。利用PLAXIS7.2有限元软件,分析了水泥搅拌桩与土锚组合支护结构的受力性能,分析表明:增加土锚使支护结构受力性能明显改善,该新型支护结构值得推广应用。同时,介绍了施工实施阶段质量控制的相应措施。According to the foundation pit supporting project of Yangzi Petrochemical Company, application of the supporting structure of cement mixing piles combined with soil anchors is introduced. The results show that the force performance is improved significantly with soil anchors by PLAXIS7.2 and combination supporting structure is worth to application. Also, the quality control measures are useful for construction of the combination supporting structure.
