摘要
以湖南浏醴高速公路红砂岩路堑段为依托,通过深入研究膨胀性红砂岩的土性、地质特征及堑坡破坏的规律和特点,提出并实施了以红砂岩边坡滑坍体为填料、土工格栅加筋并辅以综合防排水的膨胀性红砂岩路堑边坡柔性支护综合处治技术,经实践证明达到良好的支护效果。
Taking the red sandstone cutting section of Hunan Liu-Li highway as the background,through studying the soil characteristics,geological features and cutting slope damage laws and features of expansive red sandstone,the paper puts forward and implements comprehensive flexible support processing technology of expansive red sandstone cutting slope by taking red sandstone slope collapsibility as the filling material and geogrid reinforcement as the auxiliary.Practice proves that has achieved great support effect.
