Corrosion Mechanism of Similar Soil Slope Corroded by Acid Mine Drainage and its Reinforcing Treatments in Metal Mines

摘要

Based on the investigation and analysis of acid sewage quality component in some metal mine, and combining with the investigation on the engineering geology and the character of similar soil slope, the interaction and corrosion mechanism are studied between acid mine drainage and similar soil slope, it shows that the AMD changes the microstructure of rock-soil, displace and dissolve the integrant, magnify the structural scale, and hasten the new rift. The reinforcing treatments are proposed about using vetiver to consolidate the slope. The result from the practice shows that it has perfect mechanical effect using veriver to protect slope, and it is available to protect the similar soil slope, reduce the slope erosion-damage, and improve the slope stability.
