水利施工阶段性边坡开挖及防护技术研究

Study on Excavation and Protection Technology of Sope in Water Conservancy Construction Stage

边坡开挖支护施工对水利工程建设质量有着直接影响,因此本次对阶段性边坡开挖及防护技术进行深入研究。研究内容包括两个方面:一是对阶段性边坡开挖技术进行分析,包括施工前的准备工作、测量放样及边坡开挖方式选择三项内容;二是对边坡防护技术进行探讨,包括锚杆挡墙支护和锚喷支护两种支护结构。结果表明:边坡开挖及防护技术应用后,边坡稳定性较高,达到了预期目标,由此证明了本边坡开挖及防护技术的科学性和合理性。

The construction of slope excavation and support has a direct impact on the quality of water conservancy project construction.Therefore,this in-depth study on the staged slope excavation and protection technology includes two aspects:one is the analysis of the staged slope excavation technology,including the preparation before construction,survey and setting out,and the selection of the slope excavation method;the other is the slope protection The technology is discussed,including bolt retaining wall support and bolt shotcreting support.The results show that:after the application of the slope excavation and protection technology,the slope stability is high,and the expected goal is achieved,which proves the scientificity and rationality of the slope excavation and protection technology.
