摘要
引黄入晋工程利民堡段为厚覆盖区,原设计的洞线在该段红粘土层中穿过的宽度达500余米,洞线在红粘土层中穿过不利于隧洞的挖掘。为选取洞线在该区穿过的最佳位置和查明测区地质构造.开展了地震法和电测深法工作。勘查结果查明了测区地层分布和地下地质构造及赋水情况.为合理设计洞线和今后隧洞的挖掘提供了可靠的资料。
The Liminbao Section of the project of leading Huanghe River into Shansi Province is a thicky covered area. The tunnel line of the original design passes through the red clay layer of this section with a width of 500 m or more .which is unfavourable to the excavation of the tunnel. In order to select the optimum position of the tunnel line passing the area and inspect the geologic structure of this investigated area, the works of seismic exploration and electric sounding methods are conducted. The result of investigation is that the stratigraphic distribution of the underground geologic structure and the water enrichment conditions of the investigated area are manifested. Reliable data for the rational design of tunnel line and the excavation of the tunnels are provided.
