| Abstract: | Swelling rock is a common geological medium encountered in geotechnical engineering, of which the swelling-shrinkage mechanism is very complicated. The swelling-shrinkage mechanism is analysed in the paper with stress laid on the disaster caused by swelling rock in tunnel and slope engineering and the controlling treatments, which include the support of tunnel with soft wall-rock, the reinforcement of tunnel with local deformation, the treatment of tunnel floor heave and some treatment methods for slope engineering, such as dewatering, support, truncation and building up platform. It is suggested to reduce activity and increase mechanical stability of structure in tunnel and slope engineering, applying integrated method of controlling swelling and adapting swelling. |
