近年来,土石坝的修建越来越多,100米以上的高坝也相继增多。土石坝增多的原因是:设计方面土力学的飞速发展;施工技术方面碾压方法和大型施工机械的发展;对地形地质和大坝特性等的全面了解。但大坝是重要的永久性的建筑物,须保证绝对安全。因此,对坝的特性、坝体材料的性质、坝体分区以及碾压方法等有必要进行调查研究。下面介绍填筑坝的事故、发生原因以及研究采取的措施。 In recent years, more and more earth-rock dams have been constructed and high dams more than 100 meters have also been successively increased. The reasons for the increase of earth-rock dams are: the rapid development of soil mechanics in design; the rolling method of construction technology and the development of large-scale construction machinery; a comprehensive understanding of the topography and geology and dam characteristics. However, dams are important permanent buildings and must be absolutely safe. Therefore, it is necessary to investigate the characteristics of dam, the nature of dam material, dam partition and rolling method. The following describes the accident of filling dams, the causes and the measures taken to study them.
