Application Analysis of Slope Excavation and Support Technology in Water Conservancy and Hydropower Engineering Construction
水利水电工程施工中边坡开挖支护技术的应用分析

摘要

水利水电工程的边坡开挖支护是保证工程安全和施工进展的关键因素，在复杂的地形条件下进行高边坡施工存在 着严重的地质情况复杂，爆破破坏力大，地下水渗透等问题，如果应对方式不当会很容易发生滑坡、垮塌等事故，在 此背景下对水利水电工程边坡的开挖支护技术和存在的主要问题做了系统的探讨，同时从技术交底、质量检验、放样 定位、钻孔装药准备以及挂网等工作流程来说明边坡开挖的工作前准备工作，在此基础上着重介绍了混凝土喷射法、 浅层锚杆以及深层锚索三种支护方法的应用，希望可以给类似水利工程边坡的施工带来借鉴意义。

Abstract

 Slope excavation and support in water conservancy and hydropower engineering are key factors in ensuring construction safety and project progress. Under complex terrain conditions, high-slope construction faces serious challenges such as complicated geological conditions, strong blasting impact, and groundwater seepage. Improper handling may easily lead to landslides, collapses, and other accidents. Against this background, this paper systematically discusses the excavation and support technologies for slopes in water conservancy and hydropower projects, as well as the major problems encountered in construction. It also explains the preparatory work before slope excavation from the perspectives of technical disclosure, quality inspection, setting-out and positioning, drilling and charging preparation, and mesh installation. On this basis, the paper focuses on the application of three support methods: shotcrete support, shallow anchor bolt support, and deep anchor cable support. The study aims to provide reference for the construction of similar slope works in water conservancy projects.
