边坡滑坡分析及治理研究

Analysis and Treatment Research of Landslide

以昆明某高速公路滑坡为工程背景,对滑坡原因调查分析,提出两种治理方案,择优选择最佳治理方案,并通过现场实例验证得出:边坡的稳定性可从坡比、岩层界面倾角、富水性、坡面潜在程度等角度进行分析;通过稳定性、工程量和技术可行性等因素的分析来选取最佳治理方案;雨水是滑坡产生的诱因,可采取截排措施对水进行治理;边坡治理方案的设计应考虑岩层界面产状分布状况,以提高边坡的稳定性。

Taking an expressway landslide around Kunming as the engineering background,this paper investigates and analyzes the causes of the landslide,and then puts forward two controlling treatments.Preferring the optimized treatment scheme,some conclusions are come to through the field verification with instances.First of all,the slope stability should be analyzed in terms of the slope ratio,dip of rock interface,hydrous quality,and the potential extent of landslide surface,etc.Secondly,the optimum treatment scheme is supposed to be selected in accordance with the analysis of stability,engineering quantity and the technical feasibility,and so forth.What’s more,the interception and drainage countermeasures ought to be taken in regulating water conservancy for the rainwater being of the inducement of landslide.Last but not least,to improve the stability,the distribution of occurrence at the rock interface would be considered in the design of the slope treatment scheme.
