试论疏排水在红层地区滑坡治理中的重要作用

Elementary discussion on the function of water draining for landslide remediation in red beds area

红层岩土工程地质特性已为工程界所重视。由于其具有遇水软化及低强度的特性,水活动对边坡变形破坏具有重要的促进作用。论文通过对红层岩土工程地质特征和物理力学性质的分析研究,介绍了红层边坡变形破坏特征,论述了地表渗水和地下水活动对红层边坡变形破坏及稳定性的影响。并且通过工程实例分析了疏排水在红层边坡、滑坡治理中的重要作用,提出进行有效的疏排水是对红层边坡、滑坡治理加固的重要手段。

The engineering characters of red beds have been concerned by engineering experts. The water plays an important role to promote the distortion and destruct of the red beds slope, because its strength weakens when meets water.Based on studying the engineering characters of red beds, the distortiondestruct characters of slope of red beds are introduced, the effect of surface water filtering and groundwater acting on distortion, destruct and stability of slope of red beds is discussed, and the important function of draining water in remediation of red beds landslide is analyzed with engineering examples. It is emphasized that effective water draining is an important finesse in reinforcing red beds landslide.
