| 摘 要： | 黄土是第四纪大陆松散堆积物,黄土隧道具有明显的黄土工程特性.颗粒组成、含水量、微观结构、孔隙比(率)、粘粒含量、人工活动等是决定黄土的基本工程地质特征的基本因素.水胶联合是黄土颗粒之间的主要联结形式,在干燥时赋予黄土相当高的强度,但遇水后联结削弱强度降低,使得黄土具有湿陷性等特殊工程地质特性;物理地质作用、地震作用、水作用和综合作用产生黄土隧道主要工程地质灾害;水对黄土具有特殊的意义.

| Abstract: | Loess is considered a kind of mainland loose accumulation in the Quaternary Period in the paper. The Loess tunnels obviously have the loess engineering characteristic. The basic actors, which are Particulate matter, Moisture content, Mierostructure, Interstitial, Clay content, Manual work, determine the basic loess engineering characteristic. The water gum eonsociation is the main coupling form of the loess particulate, which give the very high strength in loess when loess is dry, but the coupling weakens after meeting water and the strength lowers. This is the main cause which makes loess wet collapsing. Physics geology functions, earthquake functions, the functions of water with synthesize functions are the main creation of engineering geology disasters in tunnel in loess. The water seriously impair to the loess tunnel. |
