摘要
本文阐述了小型病险水库的危害,总结了小型水库砌石坝的5个常见问题:(1)防洪标准不足;(2)溢流坝段堰型不合理;(3)坝体渗漏严重;(4)大坝下游无消能设施;(5)坝内埋管锈蚀漏水。针对上述问题,对除险加固技术进行了总结,论述了各种加固方法的特点和适用条件。从病害诱发、绕坝渗漏、防渗面板开裂、安全监测4个方面提示了除险加固过程中应注意的问题,旨在供有关小型病险水库除险加固参考。
The hazards of the small-sized dangerous reservoir are described herein,and then five common problems from the stone masonry dam for small-sized reservoir are summarized as well; i. e.（ 1） insufficient flood control standard;（ 2） unreasonable weir type for overflow dam section;（ 3） serious seepage of dam body;（ 4） no any energy dissipation facilities being arranged at downstream of dam;（ 5） embedded pipes inside of dam body being rusted with leakage. Aiming at the problems mentioned above,not only the technologies for risk-elimination and strengthening are summarized,but the performances and adaptable conditions of various strengthening methods are also discussed. Furthermore,the problems which must be paid attention to during the construction of risk-elimination and strengthening are pointed out from the four aspects of hazard-induction,seepage around dam body,cracking of anti-seepage face-slab and safety monitoring,so as to provide references for the relevant risk-elimination and strengthening of the small-sized dangerous reservoirs
