摘要
沈阳地铁2号线北延线五标位于沈阳市沈北新区,沈北新区位于蒲河冲积平原,地质情况主要以砂层、粉质黏土为主,地下水源丰富,主要以第四系空隙潜水为主。在沈阳地铁2号线北延线暗挖施工标段中,本区间为唯一的暗挖区间,区间开挖主要以标准断面为主,开挖尺寸为宽6.3米*高6.53米,采用CRD台阶法施工。
The 5-sectionfive of north extension line of Shenyang Metro Line 2 is located in Shenbei New District of Shenyang City. Shenbei New District is located in Puhe River alluvial plain. The geological conditions are mainly sand and silty clay, and the underground water is rich, mainly in quaternary pore phreatic water. In the Shenyang Metro Line 2 north extension line excavation construction section, this interval is the only subsurface excavation interval. The interval excavation is mainly standard cross-section, excavation size 6.3m wide＊ 6.53m high, CRD steps Construction of law.
