一、概况屯黄公路是屯溪机场至黄山汤口的一条新建二级旅游公路。屯黄公路加筋土挡墙位于屯黄公路K38+320～K38+380处,为双侧路肩式挡墙。挡墙全长60m,路基宽14m,挡墙两侧总长120m;最大墙高7.4 m,墙面总面积680m~2。该工程于1991年12月20日开工,1992年1月25日竣工。在此期间,我们进行了应力、应变及动静载试验。试验表明该加筋土挡墙是成功的。这是我省公路上首次采用加筋土挡墙,它的建设成功,对在我省公路建设中推广加筋土技术取得了实践经验,现将我们的具体做法介绍如下。
I. Overview Tunhuang Highway is a new two-way tourist highway from Tunxi Airport to Huangshan Tangkou. Tuen Huang Highway Reinforced Earth Retaining Wall is located at Tuen Mun Road K38 +320 ~ K38 +380, as a double-sided shoulder retaining wall. The retaining wall is 60m in length and 14m in width. The total length of the retaining wall on both sides is 120m. The maximum wall height is 7.4m and the total area of the wall is 680m ~ 2. The project started on December 20, 1991 and completed on January 25, 1992. During this period, we carried out stress, strain and dynamic and static load test. Experiments show that the reinforced earth retaining wall is successful. This is the first time in our province using reinforced earth retaining wall, its successful construction of road construction in our province to promote reinforced earth technology has gained practical experience, we will now introduce the specific practices are as follows.
