摘要
四川雅砻江两河口水电站西地220kV变电站场平工程，其位置布置在距工程坝址下游5km的右岸4。公路K2＋500一K2＋600处，工程主要在该区域建造一个84m~28nl场地，用于后期机电设备的安装；原设计是将边坡分级开挖支护后形成场地，但由于该地区属于青藏高原的雅砻江河谷地带，两岸边坡山高坡陡，其开挖工程量大，边坡下有地方公路其来往车辆及行人较多，边坡开挖过程中存在很大的安全隐患，同时由于工程施工用电的急切需要，因此业主对该场平项目工期要求很紧，根据以上要求，经反复论证最终采用预应力锚索与抗滑桩相结合的优化设计。
The 220 kV substation Changping project of Lianghekou hydropower station on the Yalongjiang River is located at Chainage K2+500-K2+600 of No.4 road,5 km downstream of the dam site.It aims to build a yard of 84 mx28 m for later erection of electro-mechanical equipment.In the original design,it is formed by steps excavation and supporting of the slope,while this area belongs to Yalongjiang valley of Qinghai-Tibet Plateau,slopes on both banks are steep with large excavation,and there are many vehicles and pedestrians passing the road every day,it exists large potential security risk during slope excavation;at the same time,due to pressing need of construction power,and the Employer has urgent requirement on the construction period of the project,therefore,optimal design of prestressed anchor rope and anti-slide pile is adopted after iterative demonstration.
