1 INTRODUCTION
The resource of bauxite is abundant in Guangxi, China, with reserves reaching about 5.15 hundred million tons. Tailings reservoir for washing tailings storage is an indispensable part of mineral mining and processing. The hydraulic transmission and wet storage are used for the bauxite tailing of Guangxi. The tailing slurry, with low permeability, high void ratio, and high water content, has the maximum moisture content rate up to more than 300% (OU Xiao-duo 2014). Because of the lack of effective drainage channel in the tailings accumulation body, the accumulation of water in the reservoir is severe. With plenty of rainfall and extremely developed karst landform, overtopping and underground karst leakage accident of Guangxi bauxite tailings dam occur frequently (LI jie-quan 2012).
