某膨胀土路堑边坡滑塌处治研究

以鄂中某地区城市主干道膨胀土路堑边坡滑塌处治为背景，对滑塌过程、成因、处治措施进行了分析，并对自然和“干湿循环”后饱和状态的抗剪强度参数进行了边坡稳定性验算。结果表明:膨胀土边坡在工程施工过程中，做好“防水、排水”工作，快速开挖、及时防护的工序衔接至关重要；采用植生袋结合防水土工布对膨胀土边坡滑塌处治具有良好效果。

Study on Treatment of an Expansive Soil Cut Slope Sliding

Based on the landslide treatment of expansive soil cutting slope of a urban main road in central Hubei , the process, causes and treatment measures of landslide have been analyzed and the slope stability checking calculation of the shear strength parameters under natural state and saturated state after the "dry-wet cycle" have been carried out. The result show that it is very important to do a good job of "waterproof and drainage" and connection of rapid excavation and timely protection in the construction process of expansive soil slope. The planting bag combined with waterproof geotextile has good effect on the treatment of landslide of expansive soil slope.
