| 摘 要： | 水泥土的强度和变形特性是影响水泥土搅拌法形成的复合地基承载力和沉降的重要因素。通过水泥土室内配合比试验,研究了不同水泥掺入量、不同养护龄期、不同土类、不同试验条件对水泥土试件无侧限抗压强度的影响,得出了不同水泥掺入量、不同养护龄期与圆柱体无侧限抗压强度的关系,对现场使用水泥土搅拌桩加固软基有较好的指导作用。

| Abstract: | The compressive strength and deformation characteristics of the cement-soil are the important factors that affect the bearing capacity and settlement of composite foundation formed by cement-soil mixing method.Through the cement-soil mixing proportion test,the paper deals with the influences of cement content,duration of curing time,soil types and test conditions on the unconfined compressive strength of cement-soil specimens,to Find out the connections of cement content and duration of curing time with the cylinder compressive strength separately.The results offer a great guideline to the use of on-site cement-soil mixing pile to reinforce the soft base. |
