摘　　要：铜陵小街地区发生岩溶性地面塌陷,危及住宅区,为此对塌陷区采取钻孔注浆方法进行处理。注入水泥,以充填岩溶洞、裂隙以及土体洞穴,增强土体强度,提高土层的承载力。文中介绍了钻孔注浆参数、施工特点及施工情况,并对注浆效果加以评价。Karst surface sudsibence dangerous to residential area occurred in Xiaojie district, Tongling, Therefore hole grouting method was used for consolidation, cement grout was injected into karsts, fissures and caverns for enhancement of strength and bearing capacity of earth mass. In this paper hole grouting parameters, engineering characters and relevant aspects were described, and grouting effect was evaluated.
