摘　　要：大坝防渗加固一直是大坝除险加固中技术难题,如何选择合适的防渗加固方案显得极其重要。文章结合实际工程案例,比选了坝基高压摆喷灌浆增设坝脚压浸平台、坝体坝基薄混凝土墙、坝体坝基高压摆喷灌浆三种方案,通过分析三种比选方案的优缺点,最终选取了经济有效的坝基高压摆喷灌浆增设坝脚压浸平台方案。采取有限元分析法复核计算了大坝防渗加固后的渗流及稳定参数,结果表明坝基高压摆喷灌浆增设坝脚压浸平台方案可行。Dam speege control has always been a technical challenge in dam reinforcement,and it is extremely important to choose a suitable plan for anti-seepage reinforcement.In the paper,based on the practical engineering cases,three alternatves including high-pressure grouting in dam foundation and platform at dam foot for immersion control,thin concrete diaphragm in dam body and dam foundation,and high-pressure grouting in dam body and dam foundation are compared,and the advantages and disadvantages of the three alternatives are analyzed.On the basis of comparison and analysis of the three alternatives,the economic and effective scheme,i.e.the high-pressure grouting in dam foundation and platform at dam foot for immersion control is adopted.The seepage and stability parameters are calculated with the finite element analysis method.The findings indicate that the scheme of high-pressure grouting in dam foundation and platform at dam foot for immersion control is feasible.
