摘　　要：太湖应天河套闸地基土性复杂,淤泥质粘土中富含有机质,土壤呈酸性。通过深层搅拌法加固套闸软基工程实例,分析了此条件下水泥土强度标准值的影响因素和取值方法,介绍了施工工艺和注意事项。工程实例表明,采取适当改进措施,深层搅拌法加固淤泥质酸性土可以达到预期的强度。The foundation soil of Yingtian River lock is complex. The muddy clay comprises organic soil and the soil is acid. Based on the practice of lock foundation consolidation by deep cement agitating method, this paper analyzes the influential factors of cement-soil strength standard and method of selecting the value, and introduces the construction technology and matters of attention. The engineering practice shows that the deep agitating method can be used to consolidate muddy-acid soil by taking improved measures.

关 键 词：淤泥质粘土 深层水泥搅拌法 水泥土 无侧限抗压强度 复合地基承载力
