Research and Application of Seepage Reinforcement Technology for Titanium Gypsum Slag Field
Titanium gypsum slag field is a by-product of titanium dioxide sulfuric acid production pro-cess.Its soil has high water content,large pore ratio,high compressibility,low strength,low water permea-bility,water expansion,water loss shrinkage and other engineering characteristics.It is easily affected by rainwater infiltration,resulting in reduced stability of slag field slope.A method of drainage and reinforce-ment of titanium gypsum slag field is proposed.The technical scheme of gravel pile reinforcement compac-tion and horizontal and vertical combined drainage is adopted to increase the overall permeability of slag field and accelerate the drainage of stagnant water inside slope.The method also improves the compactness of the soil,increases the effective stress between the soil of the slag field,reduces the slope saturation line,and improves the overall stability of the slag field.Taking a titanium gypsum slag yard as an example,the specific implementation scheme of the method is introduced,and the advantages and effects of the method are analyzed,which provides a technical reference for similar projects.
