Study on Dispersive Soil Identification for a Large Water Conservancy Project in Xinjiang
HE Qiao-yi;Xinjiang Water Conservancy & Hydroelectric Power Investigation,Design and Research General Group;
Dispersive soil refers to the cohesive soil,which repulsive force of the particle ion exceeds the attraction in saltwater with low contents or in pure water,leading to soil particle to be dispersed,it characters as low shear strength and poor scour resistance capability. Therefore,acted by extra factors of rain etc,. leaching,erosion and leakage damage occurs to the water conservancy project in the dispersive soil area. There are two typical examples of Mowel dam in Australia and West Dam in America. In addition,a large amount of caverns eroded with rain have been found as not yet stored to the Nenjiang river diversion project in southern Heilongjiang Province in China. These damages of the project brings huge losses to the nation and people,therefore,to study the soil dispersibility is are of paramount importance in the dispersive soil area.
