【摘要】 万家寨引黄工程北干线1号隧洞,长43.9km,已完成5.47km,其余洞段即将施工。该隧洞埋深较大,且大部洞身位于区域地下水位以下,工程地质条件极为复杂,通过充分分析其工程地质问题,提出隧洞掘进施工对策。更多还原

【Abstract】 1# tunnel of the North Trunk Line of Yellow River Diversion Project (YRDP) is 43.9 km long and 5.47 km of it has been fulfiled, and other tunnel sections are to be constructed. The embedded depth of this tunnel is deeper, and most of the tunnel body is below the regional groundwater level, its engineering condition is very complicated. Through analyzing its engineering geological problems, this paper puts forward some countermeasures for the construction of the tunnelling construction.更多还原
