堤防管涌险情研究进展
Research Progress on Dyke Piping
摘要
Abstract
At present, research of piping hazard mainly focuses on evolution mechanism, physical model test and numerical simulation method, as well as emergency rescue technology in flood season and non-flood season. Piping hazard is controlled by factors such as critical hydraulic conditions and formation lithology structure; however, river dynamics and continuous-discontinuous piping expansion process has not been systematically considered, and the scale effect of physical model exists. In flood season, conventional manual power is the dominant emergency treat-ment, which is obviously inefficient; in non-flood season, relief wells and cutoff wall are major countermeasures. Removable relief well has successfully solved the silting problem of traditional relief wells and significantly improved operation efficiency; vertical impermeable wall has remarkable seepage control effect, but its operation effect is dif-ficult to command due to high engineering cost and lack of monitoring and evaluation of the whole life cycle. The effect of soil-water coupling, portable-equipped emergency materials and equipment are urgent problems and re-search directions of dyke piping.关键词
