| Abstract: | Accoring exploration to expansion rock and soil of Hebei section in main canal of carrying the water from south to north, the genesis, composition and texture of expansion rocks and soils in this area are summarized, and the characteristics of pinch and swell as well as relative factors are discussed. The measures of prevention and cure to harmful geological phenomenon in this water-conservancy project put forward. Experimental methods and effects of improving the expansion rocks and soils using quick are expounded. |
