近来,各媒体在报道水灾灾情时,常使用“管涌”一词,到底何为管涌,它的危害有多大?所谓管涌是指非黏性土中,当渗流所产生的作用力达到一定程度时,可使较少的土粒逐渐随水带出,扩大土粒间的空隙,以至发生集中涌水现象。管涌往往使基础发生不均匀沉陷,可导致建筑物的破坏。 Recently, when the flood disaster was reported by various media, the term “pipe” was often used. In the end, what is the danger of pipe flooding? What is the hazard? The so-called pipe flooding refers to the non-cohesive soil where the force generated by percolation reaches a certain level To a certain extent, less soil particles can be gradually taken out with water to enlarge the space between soil particles and even concentrate the water. Piping often results in uneven subsidence of the foundations and can lead to the destruction of buildings.
