复杂地质人工骨料场高陡边坡开挖及支护施工技术研究

Study on construction technology of high and steep slope excavation and support for artificial aggregate yard in complex geology

某水利枢纽工程人工骨料场拓展区开挖边坡陡峭,高差大,地质条件复杂,断层、裂隙发育,对边坡稳定性不利。针对可能出现的不稳定状态,在边坡施工过程中采用相应的开挖、支护、监测措施,确保永久开挖边坡稳定及施工安全。

The excavation slope of artificial aggregate field in a water conservancy project is steep, the height difference is large, the geological conditions are complex, and the faults and fissures are developed, which is unfavorable to the stability of the slope. In view of the possible unstable state, the corresponding excavation, support and monitoring measures are adopted in the process of slope construction to ensure the stability and construction safety of the permanently excavated slope.
