2010年9月19日,山西省吕梁市多个县(市、区)突降大雨或暴雨,局部降特大暴雨,暴雨引发的洪水造成了较大损失。位于暴雨中心区的方山县店坪沟流域、石张流域和离石区阳坡流域坝系的71座大中型淤地坝共拦蓄洪水1 430万m3,除5座受损外其余均经受住了这场暴雨洪水的考验,突显了其在拦蓄泥沙、调节洪水、减轻灾害方面的重要作用,成为保护下游人民群众生命财产安全的坚实屏障。在此次淤地坝抗洪的过程中也暴露出了淤地坝建设管理方面存在的一些问题,针对这些问题,提出建立稳定的投资渠道、加快淤地坝除险加固步伐、坚决杜绝破坏淤地坝的行为、切实加强淤地坝防汛工作等4条建议。
September 19, 2010, Luliang City, Shanxi Province, a number of counties (cities, districts) heavy rains or heavy rains, heavy local heavy rainfall, heavy rainfall caused floods caused greater losses. A total of 71 large and medium-sized silt dam in the Dianpinggou watershed in Fangshan County, Shizhang Valley and Yangpo watershed in the Lishi area were found in the central area of the torrential rain with a total of 14.3 million m3 of floodwater, except for the 5 damaged ones The test of living in this storm and flood has highlighted its important role in halting sediment flow, regulating floods and alleviating disasters, and has become a solid barrier to the safety of lives and property of the people in the lower reaches. In the process of flood control dams, flood control dams also revealed some problems in construction management. In response to these problems, it is proposed to establish a stable investment channel to speed up the pace of dam dredging and reinforcement and resolutely put an end to damage to the site Dam behavior, strengthen silt dam flood control work and other four recommendations.
