南水北调工程具有战线长、地质复杂的特点,一个项目跨几个不同地质段的情况并不少见,对于那些可能影响渠坡稳定的地质段,必须采取相应的处理和保护措施,以保证工程建筑的安全稳定。文章简要阐述施工中遇到的湿陷性黄土、卵石透水地基、膨胀岩这几种特殊土质的处理措施。
The South-to-North Water Diversion Project is characterized by long line length and complicated geological conditions. It is not uncommon for a project to cross several geological sections. For those geological sections that may affect the stability of the drainage channel, corresponding treatment and protection measures must be taken to ensure that safe and stable. This paper briefly describes the treatment measures of collapsible loess, pebble permeable foundation and expansive rock encountered in construction.
