摘　　要：通过对不同水泥掺入比、不同龄期的水泥砂土在浸水和不浸水条件下的无侧限抗压试验,分析了浸水对水泥砂土的各项力学性能的影响,以及水泥砂土的无侧限抗压强度和模量随水泥掺入比及龄期的变化规律,并对水泥砂土全应力应变曲线的特性进行了总结。Through the unconfined compression tests on the sand soil cement with different cement ratio and different curing time, this paper analyzes variation of the unconfined compressive strength and modulus of strength of sand soil cement on the condition of soaking and un-soaking, and summarized the characteristic of stress-strain diagram of sand soil cement. Based on the conclusion in this paper, suggestions on the application of soil cement are proposed.

关 键 词：水泥砂土 抗压强度 全应力应变曲线 水泥掺入比
