摘要
广大小型水库及山塘土坝的除险加固问题是陕西省彻底消除病险水库安全隐患的重要途径。本文针对黄土地区小型土坝常见的渗漏及结构安全等病害问题,分析导致病险的原因及关键技术问题,特别指出抗震性能与坝顶交通是当前陕西省小型土坝安全评价的新问题。结合大中型土坝病险加固的经验与教训,提出黄土区小型土坝除险加固关键技术问题的对策及措施。
Removing dangers and reinforcement on earth dams of many small reservoirs and hill ponds is an important way to de- crease dangers for reservoirs. According to common problems, such as seepages and structural safety of small earth dam in lo- ess areas, some reasons and key technologies were analyzed. The paper point out that anti-earthquake performance and traffic on dam top are questions for safe evaluation on small earth dam in Shaanxi Province. According to some experiences and lessons for reinforcement and removing dangers on great and middle earth dams, some measures for removing dangers and reinforce- ment on small earth dams in loess areas were presented.
