摘要
在深厚软土地基上,是不允许建设挡水坝这样的大荷载建筑物的,随着地基处理技术的发展,人们已经可以解决许多原来不可能的问题。以达开水电站为例,研究了在深厚软弱地基上筑土石坝和混凝土面板坝的问题,通过有限元分析,说明在合理进行地基处理的条件下,在深厚软土地基上是可以兴建25 m的土石坝和面板坝,而建土石坝更加稳妥。
Generally speaking, dam can＇t be built on thick and soft groundsill. But nowadays, with the development of technique in ground treatment, many impossible engineering problems were worked out. Based on example, the paper mainly approached how to treat thick and soft groundsill on which earth-rock dam or concrete face rockfill dam was build; the results from FEM showed that 25m of these two kinds of dam may be built on thick and soft groundsill if the groundsill was well treated, but earth-rock dam was better.
