[摘要】仙居抽水蓄能电站上下水库高差达519m，其上下水库连接公路位于崇山峻岭之间，地势陡峭起伏大，植被茂密通视条件差，施工便道修建难，爆破作业管理控制难，立体交叉作业、高边坡作业、边坡挂渣滚落等安全风险大，施工环境非常复杂，进度与安全问题矛盾突出。针对实际情况，通过研究和实施现场的施工安全风险管理控制
措施，并动态优化调整，取得较好效果，具有一定的推广价值。【关键词】公路工程；设计；施工；安全技术

Abstract : The elevation difference between the upper reservoir and the lower reservoir of Xianju Pumped-storage Power Station is 519 meters. The road connecting the upper reservoir and the lower reservoir is located in mountains with much craggedness and lush vegetation which create poor visibility conditions, building difficulties for the construction access road, hard control to blasting operation, big security risks of cross-operation and high slope operation as well as slope adhering slag rolling down, difficult construction conditions and obvious contradiction between progress & safety. In view of the actual situations, the construction security risk control measures and dynamic optimization and adjustment are
applied to obtain the good effect. It has a promotional value. Key words : road construction ; design ; construction ; safety
1工程概况
仙居抽水蓄能电站总装机容量1500MW，枢纽工程属一等大（1）型工程，主要由上水库、输水系统、地下厂房、地面开关站及下水库等建筑物组成。
上下水库连接公路从新建官里桥南桥头接进厂公路，经铁门坎区域展线，回转爬升经峰门香头，继续上行至上水库副坝下方，后沿南面山坡坡面展线至上水库副项左项头：按三级公路设计，设计车速30km/h，路面宽7.0m，路基宽8.5m。路线全长
10.0km，起点高程160.2m，终点高程679.2m，相对高差519.0m，如图1所示。
