摘　　要：针对深厚软土地区影响重力式水泥土墙强度的敏感因素如水泥标号、水灰质量比、水泥掺量、养护龄期等,通过室内试验得到了多因素耦合的强度变化规律,并结合水泥土墙变形分析提出了重力式水泥土墙变形控制的有效方法,为进一步研究深厚软土地区此类支护结构的适用性和优化设计提供参考。This research evaluated the sensitive factors affecting the strength of gravity cement earth wall in deep soft soil area,including cement label,water-cement ratio,cement content,curing age,etc.The strength variation law of multi-factor coupling was obtained through the indoor test.Combined with the deformation analysis of cement earth wall,the effective method of deformation control of gravity cement wall was proposed,which is of great significance for further study on the applicability and optimization design of this kind of support structure in deep soft soil area.
