摘要
以青岛市崂山区大河东水库除险加固工程为例,通过前期专项勘察,分析浆砌石大坝渗漏部位及渗漏原因,结合施工条件,选择最佳的防渗加固方案:“防渗面层+帷幕灌浆+固结灌浆”。根据防渗加固后的工程运行效果,重点研究高水头、大涌水、裂隙密集等复杂条件下浆砌石坝的防渗加固技术。解决复杂条件下的浆砌石坝体渗漏问题,查明渗漏原因是前提,多种防渗加固方式联合应用是手段,长期运行监测是辅助,多管其下才能保障水库大坝的长期安全稳定运行。
Based on Dahedong reservoir reinforcement project in Laoshan district of Qingdao city,by special investigation in the early stage,the leakage site and leakage causes of the masonry dam are ana-lyzed.Combined with construction conditions,the optimal anti-seepage reinforcement scheme-anti-seepage surface layer+curtain grouting+consolidated grouting-is adopted.Furthermore,on the basis of operation effect of the project after anti-seepage reinforcement,the research focusing on the seepage prevention and reinforcement technology of masonry dam under complex conditions such as high head,large gushing water and dense cracks is carried out.To solve the seepage of masonry dam under complex conditions,determination of causes of seepage is the premise,combined application of various seepage prevention and reinforcement methods is the means and long-term operation monitoring is the aid.Only in this way,long-term safe operation of the dam can be guaranteed.
