摘要
滑坡是湖区堤防的常见险情之一,具有发展迅速、滑裂面较深、治理难度大的特点。本文结合工程实例分析了滑坡产生的原因,采用静力触探技术和理论分析方法推算滑裂面的位置,提出了填塘控源、块石固脚、木桩阻滑的综合治理方案。采用理论分析方法分别对沿现有滑裂面的滑动、沿桩顶的浅层滑动及沿桩底的深层滑动的稳定性进行分析计算,以验证治理方案的可靠性,可为类似滑坡的综合治理提供一定的参考和借鉴。
Landslide is one of the common dangerous situations of embankment in lake area.It generally develops rapidly with deep sliding surface and is difficult to control.Combined with engineering examples,this paper analyzes the causes of landslide,calculates the position of sliding surface by using static cone penetration test technology and theoretical analysis method,and puts forward a comprehensive treatment scheme of filling pond to control source,block stone to fix foot and wooden pile to prevent sliding.The theoretical analysis method is used to analyze and calculate the stability of sliding along the existing sliding surface,shallow sliding along the pile top and deep sliding along the pile bottom,so as to verify the reliability of the treatment scheme,which can provide some reference for the comprehensive treatment of similar landslides.
