摘要
彭水复烤厂厂房基础场平开挖后,灰岩顺层滑坡坡脚被切削,3条岩体泥化夹层相继沿切脚边坡出露,形成尺寸为250 m×230 m×20 m(长×宽×厚)的基岩顺层大型滑坡体。通过系统研究,创造性地采用沿夹层布置近水平向的截面尺寸为2.5 m×5.0 m(长×宽)的混凝土阻滑键并辅以预应力锚固的工程治理方案使滑坡体达到了稳定要求。与铅直向布置的混凝土抗滑桩方案相比,该方案节省工程投资约2/3,是一项十分有效的岩石夹层滑坡治理新型技术。
When the foundation rock at the workshop of Pengshui tobacco redrying factory is excavated, the slope foot of the limestone along-bedding landslip is cut. The three mud interlayers are exposed one after another at the slope foot, forming a huge along-bedding landslip with the size of 250 m×230 m×20 m. Through systematic research, the method setting concrete sliding resistant keys with section of 2.5 m×5.0 m horizontally and prestressed anchors is adopted to keep the slope stable. This method is very effective and 2/3 investment is saved in comparison with the method setting concrete sliding resistant key vertically.
