The Highway Construction Headquarters of Qingdao City ,Shandong Province) Abstract 　The engineering geology conditions are very complicated at the entrance slope of No. 3 tunnel , Bolai expressway that is the rock mass are broken and there are many creeps and landsides. According to the stability estimation of slope body and scheme demonstration we use the compact whole length sticky anchor post combined with grouting technology and extendod dischargc technique for the slope treatment. Thus ,the self bearing capacity of slope rockmass is greatly increased and the rockmass retaining wall is formed accordingly. This provides the experience for the future similar slope treatment. Keywords 　slope ;rockmass modification ;rockmass retaining wall ;protection 原设计方案进行了调整。 1 　序言 #
