公路膨胀土路基变形预测与控制方法

On roadbed deformation prediction of road expansive soil and its controlling methods

介绍了膨胀土路基湿胀变形计算的方法,分析了膨胀土路基自身平衡含水率的预估方式,提出了膨胀土路基刚度补偿设计的措施,从而避免路基变形破坏现象的发生。

The paper introduces the methods for the deformation calculation of the swelling of the expansive soil roadbed, analyzes the pre- estima-tion means for the water content of the self-balance of the expansive soil roadbed, and points out the measures for the stiffness compensation design of the expansive soil roadbed, so as to avoid the damages by the roadbed deformation.
