| 摘 要： | 为了克服盐渍土填料对路基带来的不利影响,通过抗剪强度、无侧限抗压强度和抗压回弹模量试验对掺加不同量的石灰粉煤灰改良土的力学性能进行了研究。结果表明:掺加一定量石灰粉煤灰可以提高盐渍土填料的粘聚力和内摩擦角,填料后期无侧限抗压强度和抗压回弹模量也随石灰粉煤灰掺量的增加而增加。

| Abstract: | In order to eliminate the adverse effect on subgrade caused by saline soil filling,through shearing strength,unconfined compressive strength and compression resilience modulus test,this paper studies the mechanical performance of the improved soil mixed with lime-flyash of different proportions.The result indicates that a certain amount of lime-flyash can strengthen cohesive strength and increase inner frictional angle of saline soil filling,and unconfined compressive strength and compression resilience mod... |
