| 摘 要： | 以已建的20余座黄土隧道为背景，调查分析了黄土隧道典型的工程地质和水文地质条件，总结了相应的支护方案和施工方法以及存在的工程问题，并进行了原因分析。结果表明：塌方是黄土隧道的主要工程问题，隧道周围汇水长廊的形成是黄土工程问题产生的主要原因，隧道进出口段和地质条件发生突变的地层是工程问题发生的主要部位

| Abstract: | In light of the built loess tunnels, the engineering geology and hydrogeological conditions have been investigated and analysed. Some support measures and construction methods have been summarized. Meanwhile the engineering problems for loess tunnels have been pointed out. It is shown that the collapse is the main project problem. The main cause making engineering problems is the gather water corridor around tunnels. The main positions of destruction is import and export segments and the stratum in which the geological conditions would be changed suddenly. |
