摘要
目前,世界上尚无有关建造在狭窄河谷上的200m以上高面板坝的报道。本文利用三维非线性有限元分析方法,结合一座拟建中的河谷宽高比仅为1.88的225m高的面板堆石坝,对坝体的变形和应力进行数值计算,对狭窄河谷上建设的高面板坝可能存在的问题进行了探讨。分析了狭窄河谷的拱效应对大坝的变形和应力的影响,建议了相应的工程措施。
At present, it is not reported that constructed CFRD is higher than 200m in narrow valley. In this paper, combining with the designed 225m high CFRD with the rate of valley width to height being 1.88, comprehensive numerical analysis is performed to predict the deformation and stress characteristics during construction and reservoir fulfilling by three dimensions nonlinear FEM. Prospective problems are discussed in high CFRD built in narrow valley, the arching effect on dam＇s deformation and stress is analyzed and the corresponding engineering measure is proposed
