摘要
本工程涉及大型土石方开挖及高边坡支护工程施工,地处山区,工程地质条件复杂。边坡设计高度落差71m,边坡开挖采取分级开挖,锚索施工紧随边坡分级开挖施工,支护工程采用预应力锚索、锚杆与边坡混凝土格构梁形成一整体,利用锚索、锚杆与岩层的抗摩擦力来抵抗山体边坡产生的不良位移。工程建设取得了良好的社会效益及经济效益。
This project involves large earthwork excavation and high slope supporting engineering construction,located in the mountainous area,complicated engineering geological conditions. Drop height 71 m design of side slope,the slope excavation adopt grading excavation,anchor cable construction in the wake of the hierarchical slope excavation and support support engineering with prestressed anchor cable,anchor and slope concrete lattice frame beam to form a whole,with anchor,bolt and rock friction resistance to resist adverse displacement of slope. Construction of the project has achieved good social and economic benefits.
