| 摘 要： | 膨胀土的反复胀缩变形及强度衰减特性,对路堑边坡具有长期潜在的破坏作用,而刚性防护措施难以解决此类问题。通过配制一种新型的液体改良剂,对膨胀土边坡进行化学喷洒渗透改良,使之形成结硬的表面封闭层,使边坡长期处于稳定状态,成功实现了膨胀土路堑边坡的柔性防护,为膨胀土路堑边坡处理提供了新途径,具有较好的推广应用价值。

| Abstract: | Properties of strength reduction and repeated expansion and contraction deformation of expansive soil produce long-term potential destruction on roadcut slope of expansive soil,it is difficult for using measure of rigid protection to solve the problem.A new type liquid amendment agent is made to spray on roadcut slope.So the hard sealing coat is formed to ensure stability of roadcut slope.Then a successful way which has greater value for treating expansive soil is presented and application is carried out to protect the slope flexibly. |
