| 摘 要： | 针对大板水库大坝防渗效果较差问题,提出了坝体混凝土防渗墙+坝基帷幕灌浆的防渗加固方案及高压旋喷墙+压力充填灌浆的质量缺陷补强措施,并对大坝防渗加固前、后进行了有限元渗流分析。实际运行结果表明,加固及其补强措施总体效果显著。

| Abstract: | In view of the poor effect of seepage prevention for dam body of Daban reservoir,the strengthening schemes of seepage prevention is put forward by combination of concrete cutoff wall of dam body and grouting water-tight screen of dam foundation.In addition,the remedial measure of quality defects is proposed by high-pressure rotary spray wall and pressure-filling grouting.Finally,the finite element seepage analysis is compared with or without seepage prevention strengthening of the dam.The actual operation r... |
