1工程概述 杭州市解放路隧道由两座分离式小间距隧道组成,埋深在地面以下5m;隧道轮廓采用三心圆,净宽10.628m,净高6.572m。在沪杭线下行K200+942.5与铁路相交,交角80°,相交处为杭州站沪端咽喉区,共有正线2条、牵出线1条、渡线2条,作业繁忙。隧道洞身穿过富水砂质粉土层,采用铁路线路加固下的浅埋暗挖法(CRD工法)施工,施工难度大。
1 Project Overview Hangzhou Jiefang Road Tunnel consists of two separate small-spaced tunnels, buried at a depth of 5m below the ground; tunnel profile with three heart-round, net width of 10.628m, a net high of 6.572m. In the Shanghai-Hangzhou line down K200 + 942.5 and the intersection of the railway, the intersection angle of 80 °, the junction of Hangzhou Station Shanghai side throat area, a total of two positive lines, pulling a line, crossing 2, busy operation. Tunnel tunnel through the sandy silt layer of rich water, the use of the railway line under the reinforcement of shallow burial method (CRD method) construction, construction difficult.
