分散性土作为坝料的一些问题
Problems on Dispersive Soil as Dam Materials
-
摘要: 从1961年开始,澳大利亚首先发现某些粘土在水中有不同程度的分散性,并认为这是许多土坝所以失事的一个重要原因。这个发现引起了其他国家的重视,美国在七十年代也紧跟着澳大利亚之后,从野外调查、室内试验以及补救措施等各方面来研究分散性土料的筑坝问题,获得良好成果。 由于国内对这一课题尚未有足够的认识和重视,笔者搜集了澳大利亚英格尔斯(1ugles)教授来华讲学时所赠文献,及最近美国、加拿大等国家在这方面所发表的论文,将分散性土的性状、试验方法、试验成果的整理、分散性土作为坝料事故以及阻止事故的方法等汇总成文,供国内水利界参考。我国急起直追,犹为未晚。Abstract: Dispersive Soil was first discovered by Australians in 1961. Then extensive studies were carried on in Australia during 1960's and in U. S. A. during 1970's. These studies included field investigation, laboratory testing and remedy measures and gained good achievement.Because we have not paid much attention on dispersive soil in China, it is main purpose of the writer to summary the current progress of dispersive soil problems from recen papers published in Australia, U. S. A. and Canada including the papers to be supplemented privately to the writers by Prof.O.G.Ingles, and to condense them into a convenient reference for hydraulic engineering circle in this country.
