武汉老粘土地区土钉墙破坏形式及其防治措施

The Pattern of Soil Nail Wall Destroying in Old Clay Area of Wuhan and Prevention Measures

在分析老粘土的矿物成份及结构特点的基础上,阐述了老粘土的工程地质特性及基坑破坏形态.通过工程实例,说明采用复合土钉墙支护技术处理老粘土地区边坡滑移是十分有效的措施,为类似地层基坑支护和抢险提供可借鉴的方法.

By analyzing mineralogical compositions and structure characteristics of Old Clay, this paper expounds the engineering geological specialty and pattern of foundation pit destroying in old clay layer. A project example shows that composite soil nail support was effective to prevent slope sliding accident, which provides references to foundation pit support and rescue work in similar clay area.
