| 摘 要： | 针对多雨地区路基湿度增加,对土体抗剪强度特别是其中土颗粒之间粘聚力的影响,提出复合碎石排水层的解决方案。为了使复合碎石排水层达到最佳排水效果,进行了试验段施工,并在试验段内埋设湿度传感器。检测结果表明：设置复合碎石排水层以后,能有效减少外界水对路基的干扰,维持路基水稳定性。

| Abstract: | Aimed at the impact on the shear strength of soil,especially the cohesion among the particles by the increasing of humidity of subgrage in rainy areas,a solution of compound gravel drainage layer was proposed.In order to achieve the best drainage effect,a test section was constructed and several humidity sensors were buried along with it to run the humidity test.The results show that by setting compound gravel drainage layer,the interference of outside water on the subgrade is reduced,and the water stabilit... |
