黄土质隧道的工程特性

Engineering characteristic of loess tunnel

通过分析黄土的特征、分布及其工程地质性质,研究了黄土隧道的设计特点,总结了黄土隧道施工的技术要点,并指出黄土隧道施工必须坚持的原则,通过采用动态的初期支护分步施工,从而达到围岩与支护共同受力和快速施工的目的。

Through the analysis of the characteristics and the distribution of the loess, and the engineering geological properties, the paper studies the design features of the loess tunnel, summarizes the technical points of the construction of the loess tunnel, and points out that the principles should be adhered to in the construction of the loess tunnel, to achieve the goal of the combined force of the surrounding rock and the support, and the rapid construction by using the dynamic preliminary support fractional steps construction.
