随着国家经济的持续发展,水利工程建设的规模也在不断扩大,其中挡水建筑物也变得越来越重要。土石坝在挡水建筑物中的运用非常广泛,其渗流破坏问题也就显得至关重要,相关资料显示,由于渗透破坏引起的土石坝事故约占30%,因此渗流是影响土石坝安全的主要因素。本文对渗流破坏机理进行了分析,并提出了渗流控制的基本内容和控制措施。
With the continuous development of the national economy, the scale of water conservancy projects is also constantly expanding, of which water retaining structures are also becoming more and more important. The application of earth-rock dams in retaining structures is very extensive, and the problem of seepage failure is also very important. Relevant data shows that the seepage is the main factor affecting the safety of earth-rock dams due to the earth-rock dams caused by infiltration and destruction about 30% factor. This paper analyzes the failure mechanism of seepage and puts forward the basic content and control measures of seepage control.
