对于水利水电工程项目来说,往往在建筑物上方存在一定的危岩体,危岩体在地震、开挖放炮、裂隙水等外力作用下可能垮塌,威胁着下方建筑物、设备及人员的安全。危岩体一般分布在高程较高部位,对其治理存在设备材料运输困难、安全风险高、支护施工技术难度较大等问题。本文通过对具体高边坡危岩体支护施工的特点及施工过程、方法、问题的解决等方面进行描述,以达到学习和推广的效果。
For water conservancy and hydropower projects, there is often some dangerous rock mass above the buildings. The dangerous rock mass may collapse under the external forces of earthquakes, excavation and blasting water, which threaten the safety of the buildings, equipment and personnel below. . Dangerous rock mass is generally distributed in the upper part of the elevation, there are problems such as difficult transportation of equipment and materials, high safety risk and difficulty of supporting construction technology. This paper describes the characteristics of the construction of dangerous rock mass supporting high slope and describes the construction process, methods and problems to achieve the effect of learning and promotion.
