摘要
以吉林省某施工工地取低液限黏土为试验土样,在不同掺灰量、不同粒径、不同冻融循环方式条件下,进行不固结不排水抗剪强度试验.本文以素土和掺灰5%石灰处治土为主要研究对象进行试验.试验结果表明,养生7d再次冻融石灰处治土的抗剪强度优于未养生直接冻融的抗剪强度;相同压实度下,抗剪强度随着粒径的增大而减小;在相同粒径条件下,抗剪强度随着围压的增大而增大.
Through indoor triaxial compression test and modulus of resilience test. With initial elastic modulus and the resilient modulus of lime treated subgrade soil are tested. The results showed that： Lime dosage on the initial elastic modulus and resilient modulus. With the increase of the mixed with lime content,both modulus are increased.The equation about fitting relationship with the initial elastic modulus and resilient modulus is proposed. For the application of initial elastic modulus can be more accurate in engineering provides the basis.
