摘　　要：本文结合某水泥搅拌桩复合土钉支护工程实例，阐述了在水泥搅拌桩中植入微型钢管桩补强技术的加固原理和实施方法。实践表明，两者结合作为水泥搅拌桩强度不足时的补强措施，施工简便、工期短、安全可靠，是解决基坑局部安全问题的推荐方法。This article combines with cement mixing pile composite soil nailing support project as an example, elab-orates the reinforcement principle and implementation method by embedding micro steel pipe piles reinforcing technology in the cement mixing pile. Practice shows that combination of these two ways as the reinforcing measures when the cement mixing pile reinforcing measures are insufficient. Convenient construction, short time limit, and safe and reliable are the recommended methods to solve the problem of foundation pit local security.
