| 摘 要： | 当黄土分布区地下水埋深较浅时,黄土常呈饱和状态,不具湿陷性,简称饱和黄土,甘肃引洮供水一期工程总干渠13#、14#、15#隧洞通过饱和黄土,通过常规土工和扫描电子显微镜等综合测试,对饱和黄土的显微结构及化学成分进行了研究,并探讨了其微观结构与物理力学性质及工程特性之间的关系,认为应选择盾构法进行饱和黄土隧洞开挖。

| Abstract: | Loess is usually in a saturated state and is called saturated loess when groundwater level is shallow.The 13~(th)、14~(th)、and 15~(th) tunnels of the main canal for the first phase of Yintao Water Supply Project in Gansu pass through saturated loess stratum.The author analyzed the microstructure and chemical composition of saturated loess by comprehensive geotechnical tests and scanning electron-microscope.Based on the derived relationship among its microstructure,the physical-mechanic properties and engineering characteristics,the author recommended that shield method be adopted in excavation of the saturated loess tunnel. |
