摘　　要：河北丰宁抽水蓄能电站下水库进/出水口边坡首先通过理论计算,在开挖前初步确定了边坡的锚喷支护参数,在施工过程中,根据揭露的实际地质条件、监测资料、施工状态及开挖跟踪反分析和围岩稳定分析结果,采取了针对性的边坡加强支护措施,并利用Geostudio和理正岩土软件对加强支护后的高边坡进行稳定性复核计算,优化和完善了合理的边坡支护参数,在确保施工安全的前提下有效降低了建设成本,使工程安全经济,其成果对工程应用及类似边坡的防护措施有指导和借鉴意义。Firstly,through theoretical calculation,the anchor shotcrete support parameters of the lower reservoir inlet/outlet slope of Fengning pumped storage power station in Hebei Province are preliminarily determined before excavation.During the construction process,according to the exposed actual geological conditions,monitoring data,construction status,excavation tracking back analysis and surrounding rock stability analysis results,targeted slope strengthening support measures are adopted,and geostu is used Dio and Lizheng geotechnical software are used to recheck the stability of the high slope after strengthening the support,optimize and perfect the reasonable slope support parameters,effectively reduce the construction cost under the premise of ensuring the construction safety,and make the project safe and economic.The results have guidance and reference significance for engineering application and similar slope protection measures.
