Expansive soil slope protection method
The invention provides an expansive soil slope protection method, which belongs to the technical field of slope protection. The method comprises the following steps: S1 the water content of an expansive soil slope is measured, and an atmospheric influence range value is determined; S2 the slope top and the slope surface of the self-expansive soil slope are excavated, a plurality of step surfaces are formed, and the excavation depth is larger than the atmospheric influence range value; S3 the step surface is covered with geomembranes, and the geomembranes are arranged on the step surface in a stepped shape; S4 multiple soil engineering bags are all filled with backfill soil, the multiple soil engineering bags are divided into multiple sets, and the sets of soil engineering bags are laid on the geomembranes in a layered mode and located above the step surface; and S5, the sides, away from the expansive soil slope, of the multiple sets of soil engineering bags and the upper ends of the multiple soil engineering bags located on the uppermost portion are covered with protective layers correspondingly. According to the expansive soil slope protection method, the expansive soil slope is effectively prevented from cracking, and the landslide phenomenon is avoided.
本发明提供了一种膨胀土边坡防护方法，属于边坡防护技术领域，包括S1：对膨胀土边坡进行含水量的测量，确定大气影响范围值；S2：自膨胀土边坡的坡顶和坡面挖掘并形成多个台阶面，且挖掘深度大于气影响范围值；S3：使用土工膜覆盖台阶面，且土工膜呈阶梯状随形布置于台阶面上；S4：在多个土工袋内均填充回填土，将多个土工袋分为多组，且各组土工袋分层铺设于土工膜上，且位于各台阶面的上方；S5：在多组土工袋远离膨胀土边坡的一侧和位于最上方的多个土工袋的上端均覆盖安装保护层。本发明提供的膨胀土边坡防护方法，有效地防止膨胀土边坡出现裂缝，也不会产生滑坡现象。
