摘要
为研究干湿循环效应对石灰处治膨胀土强度特性的影响规律,文章通过一系列室内物理力学性质试验获取膨胀土改性前后的物理力学性质指标,并借助GDS动三轴仪对处治土开展振动三轴试验,研究干湿循环效应下石灰处治膨胀土的动力响应特征,对合理的路堤边坡防护、路面结构设计和养护具有指导意义。
In order to study the effect law of dry-wet cycle effect on the strength characteristics of lime-treated expansive soil,this article obtained physical and mechanical properties indexes of expansive soil before and after the modification through a series of indoor physical and mechanical property tests,and carried out the vibratory triaxial tests of treated soil via to GDS dynamic triaxial apparatus,to study the dynamic response characteristics of lime-treated expansive soil under the effect of wet-dry cycle,which has guiding significance for reasonable embankment slope protection,pavement structure design and maintenance.
