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。
Beginning in 1961, Australia first discovered that some clays disperse to varying degrees in water and consider it an important cause of the failure of many earth dams. This discovery aroused the attention of other countries. After the United States followed Australia in the 1970s, the United States has made good achievements in researching the dam construction of dispersed soil materials from the aspects of field investigation, laboratory tests and remedial measures. Due to the fact that there is not enough understanding and emphasis on this subject in China, I collected the documents donated by professors 1ugles from Australia when giving lectures in China and recently published papers by the United States and Canada in this field. Disperse soil properties, test methods, the preparation of test results, disperse soil as a dam accident and the method to prevent accidents and other documents written for the domestic water community reference. My country catch up, it is not too late.
