摘　　要：引汉济渭二期工程白鹿塬隧洞地质条件复杂,地下水位高,稳定性极差,施工难度大,隧洞能否如期贯通也制约着调水工程效益的发挥,因此选择合理的施工方案至关重要。结合隧洞的水文地质条件,对采用全线常规法、全线盾构法、盾构法+常规法接应联合施工三种方案进行分析比选,确定盾构法+常规法接应联合施工方案,在工期最优的前提下,工程投资较省、质量有保证、施工风险低、环境影响较小。The Bailuyuan tunnel of the second phase of the Han-Ji-Wei diversion project has complex geological conditions, high groundwater level, extremely poor stability, and difficult construction. Whether the tunnel can be completed on schedule also restricts the benefit of the water transfer project, so it is very important to choose a reasonable construction plan. Combined with the hydrogeological conditions of the tunnel, three schemes of joint construction using the full-line conventional method, the full-line shield method, and the shield method + conventional method are analyzed and selected.Determine the joint construction scheme of shield method + conventional method. Under the premise of optimal construction period, the project investment is relatively low, the quality is guaranteed, the construction risk is low, and the environmental impact is small.
