焦柳线红砂岩地质水害工点整治

摘要

针对红砂岩地质易风化崩解,遇水泥化的特点,结合焦柳铁路K670＋000-K688＋500段水害整治工程具体实践,分析红砂岩地质水害形成原因,提出红砂岩地质坡面防水处理、坡脚基础加固防冲刷以及合理引导地表排水防渗漏的整治方案,并对红砂岩地质条件下铁路防洪工作展开思考和建议。%Against red sandstone geology having characteristics of easy weathering,easy disintegration and argillization,this paper,combined with the practical work of water disaster treatment project at the K670＋000-K688＋500 Section of Jiaozuo-Liuzhou Railway,analyzes the causes forming geological water disasters in red sandstone area and proposes the treatment scheme with respect to waterproofing work on slope surface in red sandstone geology,reinforcement of slope foot foundation for scour-prevention and proper guidance of surface drainage for leakage-prevention;moreover,the thinking and suggestion on flood control for railway under such conditions is conducted.
