摘要:
陆浑灌区运行10多年来,在豫西抗旱斗争中发挥了巨大的作用由于群众性施工,运行期间事故率高,特别是灌区的数百座填方坝,原施工质量较差.针对填方坝的局部稳定问题,利用有限元方法计算多种方案的渗流要素,以及坡面自由出渗和坡面淹没出渗情况下的临界坡降值,分析了填方坝局部稳定状况,认为基本不能满足局部稳定要求,主要原因是:施工质量差,坝体密实度不够,裂缝多且贯通,使渗流流速和水力坡度偏大,冲起坡面土料而失稳.解决方法是通过灌浆等措施增大坝体密实度,坝面增设滤层或培厚.
Abstract:
Luhun irrigation area has been in operation for more than 10 years, and has played a huge role in the drought resistance struggle in western Yuxi, due to mass construction, the accident rate during operation is high, especially the hundreds of filled dams in the irrigation area, and the original construction quality is poor. Aiming at the local stability problem of the filled dam, the finite element method was used to calculate the seepage elements of various schemes, as well as the critical slope drop value under the condition of slope free infiltration and slope inundation, and the local stability of the filled dam was analyzed, and it was concluded that it could basically not meet the local stability requirements, mainly due to: poor construction quality, insufficient dam compactness, many cracks and penetration, so that the seepage flow rate and hydraulic slope were large, and the slope soil was washed up and unstable. The solution is to increase the compactness of the dam body through grouting and other measures, and add a filter layer or thicken the dam surface.
