摘 要:结合江西某矿山污水库的水质分析和现场物探结果,分析了矿山酸性污水对防渗帷幕的腐蚀机理,制定了采用粉煤灰的混凝土垂直防渗墙的抗腐防渗措施。实践证明:该抗腐防渗方案是可行的,能够有效提高土石坝防渗帷幕的抗酸耐久性能,可供类似工程项目推广应用。Combined with the water quality analysis and the result of geophysical investigation in the site from a mine wastewater reservoir in Jiangxi province,the erosion mechanism of mine acid wastewater on anti-seepage curtain is analyzed.The anti-corrosion and anti-leakage measure of the concrete vertical anti-seepage wall mixed with the pulverized coal ash is proposed.The result of the practice shows that the scheme of the anti-corrosion and anti-leakage is feasible,and the quality of anti-acid and durability of the anti-seepage curtain of the earth-rock dam can be effectively improved,and can be popularized and applied in the similar engineering projects.
