马堵山水电站工程发电厂房后边坡设计

摘要

马堵山水电站后边坡最大坡高约120 m，工程边坡具有分布范围广、坡高且大部分构成顺向坡、地质条件复杂等特点。通过现场地质调查结合边坡参数反演分析计算，并结合当地工程经验制定边坡设计方案，现场实施效果良好。工程完工运行多年，现场监测数据表明设计方案安全可靠；文中边坡支护设计思路及边坡处理方案对同类工程的设计工作具有一定的参考意义。%The maximum slope of powerhouse in Madushan hydropower project is about 120m high.It has a wide distribution of complex geological conditions, and the slope has an outside tendency.The slope design scheme is improved with field geological investigation, inversion analysis of slope parameters and the local engineering experience.The project has been completed for years. The in-situ monitoring data shows that the design scheme is safe and reliable.The slope design ideas and scheme have certain reference significance to similar project design work.
