摘要
在陡峭的山崖上一500 m3左右的不稳定岩体,已呈倾斜状态,其下方高差100多m处有三峡电力外送的50万V超高压线路铁塔及村庄,安全受到严重威胁。在其他处理手段难以实施的情况下,采用在多种安全防护下的控制爆破成功地加以清除。介绍的技术方案和防护措施,可供类似地质灾害防治工程参考。
A rock alongside the steep cliff which is a danger to near villages and high-vohage line will be cleared, a contolled blasting was successfully implemented in multiple protection measures. The technological pro- gram and protection measures are introduced. The experiences can be referred by similar engineering.
