摘    要:挪威进行了一项完整的关于不同筑坝材料的土石坝稳定研究项目,以研究小坝的溃决问题.现场实验结果表明,碾压堆石坝的抗剪强度要高于常规稳定分析结果,坝脚处实际的抗水流冲刷能力较强.当坝体下游外部发生冲蚀时,过程较慢,当冲蚀深度发展到坝顶的上游坡面时,溃决过程很快,溃口先向下发展直到坝脚,然后才向两侧发展.

关 键 词:溃坝  坝体  流量

Abstract:In order to study issues related to small dam-break, a series of studies about the stability of earth-rock dams that use varies materials for dam construction were conducted in Norway. On-site experiment results display that the shear strength of rolled rockfill dam is higher than the conventional analyzing results. In fact the scour resistance capacity is relatively strong at the dam toe. When erosion takes place at the lower reaches side of the embankment, process is slow; however, when erosion develops to the upper reaches slope on the dam top, the breaking process tends to be fast. The breaking is developed from the top to the dam toe and then to the both sides.
Keywords:dam-break  embankment  discharge
