联合加固技术在青山水库大坝左岸边坡加固中的应用

Application of joint reinforcement technique in the slope reinforcement of the left bank of Qingshan Reservoir

随着水利水电工程建设向地质复杂地区推进,单一的加固措施已经不能满足大型边坡加固的需求。本文以辽宁省葫芦岛市青山水库大坝左岸边坡为例,提出以锚杆、抗剪洞为主,辅以其他加固方式的联合加固措施。工程实践显示,锚杆早期发挥抗剪能力,抗剪洞可以在边坡滑动破坏过程中发挥重要作用,两者的协调作用可以大幅提升边坡加固的工程效果。

Single reinforcement measures cannot meet the needs of large slope reinforcement with the development of water conservancy and hydropower project construction to regions with complex geology. In the paper,the left bank slope of Qingshan Reservoir dam in Huludao of Liaoning Province is adopted as an example to propose a joint reinforcement measure based on anchors and shear holes and supplemented by other reinforcement methods. Engineering practice shows that anchor can play the shearing ability in early stage. The shear hole can play an important role in the process of slope sliding failure. Coordination role thereof can greatly improve the engineering effect of slope reinforcement.
