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。
Repeated expansion and contraction of expansive soil deformation and strength attenuation characteristics of the cutting slope has long-term potential for damage, and rigid protective measures are difficult to solve such problems. Through the preparation of a new type of liquid modifier, the expansive soil slope is chemically sprayed and infiltrated to form a solidified surface sealing layer, so that the slope is in a stable state for a long time, and the flexible protection of the expansive soil cutting slope is successfully achieved , Which provides a new way for the treatment of expansive soil cutting slope and has good popularization and application value.
