摘要

以粉土和4 %石灰、2 %水泥+2 %石灰、4 %SEU-2型固化剂、8 %SEU-2型固化剂处理的粉土为研究对象，通过不固结不排水三轴剪切试验(UU)和固结不排水三轴剪切试验(CU)对变掺量、变龄期条件下粉土及稳定土的强度和变形特性进行了研究。试验结果表明：粉土及其稳定土的应力-应变曲线主要为软化型。SEU-2型固化剂在改善粉土的凝聚力方面起了很好的作用，综合考虑了不同稳定方法的强度指标，表明掺SEU-2型固化剂是稳定粉土的最有效的方法。

Abstract

Silts and silts treated with some additives are studied. These additives include 4 % lime

2 % cement and 2 % lime

4 % SEU-2 solidified agent

and 8 % SEU-2 solidified agent

respectively. Unconsolidated undrained triaxial tests and consolidated undrained triaxial tests are used to study characteristics of strength and deformation of silts at various ages and with different additives. Test results show that the stress-strain curves of silts and stabilization silts are primarily softening

and that SEU-2 solidified agent can apparently improve the cohesion of silts. Comparing the strength parameters of stabilization silts treated with different additives

it is considered that adding SEU-2 solidified agent is the most effective method to stabilize silts.
