上官寨隧洞开挖对后缘边坡影响分析

Analysis on Influence of Excavation of Shangguanzhai Tunnel on Trailing Edge Slope

随着国民经济的快速发展和西部大开发战略的实施,水利水电工程在西部地区得到了大力开发。隧洞作为水利枢纽中重要的组成部分,在开挖过程中爆破震动对隧洞本身及周围有一定影响。分析隧洞开挖过程中对山体边坡的影响,提出开挖过程中保证隧洞和山体边坡稳定的技术措施,以期为隧洞建设提供借鉴。

With the rapid development of the national economy and the implementation of the strategy of developing the western region, the water conservancy and hydropower project has been vigorously developed in the western region.The tunnel is an important part of the water conservancy project. During the excavation process, the blasting vibration has certain influence on the tunnel itself and its surroundings. In this paper, the influence of tunnel excavation on the slope of the mountain is analyzed, and the technical measures to ensure the stability of the tunnel and the slope of the mountain during the excavation process are proposed to improve the quality of the tunnel construction.
