不同断面下高速公路隧道造价及影响因素分析
2016.06.15点击：
标及其单位造价水平进行比较分析, 研究在支护参数不变的情况下，断面变化对工程造价的影响，考虑断面在界限宽度每增加0.25m 0.5m及0.75m时，隧道每延米造价的变化，并通过分析寻找影响隧道单位造价变化的主要因素。

Abstract:In this paper, four kinds of the main indicators of quantities and the unit cost level which are commonly used in different clearance of two lane shallow-depth-excavation highway tunnels have been comparatively analyzed. In the case of supporting parameters unchanged, the influence of cross section changing on the project cost has been researched. When the line width increases of 0.25m, 0.5 m and 0.75 m, the changes of per linear meter cost in tunnel have been considered. And according to analysis, the main factors which are affecting the change of unit cost in tunnel have been found.
