Rock slope excavation method
The invention discloses a rock mass slope excavation method, which comprises the following steps of: excavating to the front of a designed excavation structure line, reserving a reserved protective layer with the thickness equal to or greater than 3M, and finishing excavation of the reserved protective layer after anchoring anchor rods are constructed on the reserved protective layer; the method specifically comprises the steps of excavation construction before reserving a protective layer, construction of a pre-anchoring system and excavation construction of the reserved protective layer. The slope excavation method is practical in technological process and high in feasibility, excavation is conducted after the unstable slope is anchored in advance, the traditional slope excavation process is broken through, and major potential safety hazards such as bedding slippage and collapse occurring in a common excavation method are made up to a great extent; the slope excavation method is suitable for unfavorable geological slope excavation, and is particularly suitable for excavation of inclined rock slopes, particularly inclined rock slopes, along slopes of dam foundations of hydropower stations and slopes with high requirements on the integrity of excavation structure lines.
本发明公开了一种岩体边坡开挖方法，岩体边坡开挖采用开挖至设计开挖结构线前，预留厚度等于或大于3M的预留保护层，在预留保护层施工锚固锚杆后再完成预留保护层的开挖；具体包括：预留保护层前开挖施工、预锚系统施工和预留保护层开挖施工。本发明边坡开挖方法工艺流程实用，可行性高，通过预先将不稳定边坡进行锚固后再开挖，打破了传统边坡开挖的流程，极大程度上弥补了在普通开挖方法中出现的顺层滑移、坍塌等重大安全隐患；本发明适用于不良地质边坡开挖，特别适用于倾斜、特别是倒倾岩体边坡、水电站坝基顺边坡开挖、及对开挖结构线完整性要求较高的边坡开挖。
