复杂山地建筑群边坡组合支护技术

Support Technology of Slope Combination in Complex Mountain Building Group

针对重庆首创鸿恩寺建筑密集,边坡形态超长、超高以及地质复杂、地势陡峭、岩质复杂的施工环境,通过重力式挡墙分阶、基坑内排水、基坑外排水、调整锚索角度、地表排水、边坡内部泄水、挡墙设伸缩缝、封闭凹岩腔等方式提高边坡稳定,且保证安全施工。

In view of the construction environment of building density,ultra-long slope shape,ultra-high height,geological complexity, steep terrain and complex rock quality in Chongqing Shouchuang Hongensi. Slope stability can be improved by means of gravity retaining wall steps, drainage in foundation excavation,adjustment of anchor cable angle,surface drainage,internal drainage in slope,expansion joints in retaining wall,and sealing concave rock cavity,and ensure safe construction.
