某高面板堆石坝设计与研究

Design and Research of a High Face Rockfill Dam

混凝土面板堆石坝是一种安全经济的坝型,对地形、地质和气候条件有广泛的适用性,在世界范围内得到了广泛的应用,近几十年来得到迅速的发展。本文对某高面板堆石坝进行了设计,采用邓肯张e-b模型,使用通用岩土分析软件MIDAS GTS NX软件对大坝建立了三维模型,拟定三种参数方案,对面板堆石坝的应力与变形进行了分析,确定了最优参数方案,得到了大坝在竣工期及蓄水期的应力与变形,分析结果对工程设计优化、类似工程借鉴、保证工程安全具有一定的参考价值。

Concrete faced rockfill dam is a kind of safe and economical dam type,which has wide applicability to terrain,geology and climate conditions,has been widely used in the world,and has been rapidly developed in recent decades.In this paper,a high faced rockfill dam is designed,a three-dimensional model of the dam is established by using Duncan Zhang e-b model and MIDAS GTS NX software,a general geotechnical analysis software,three parameter schemes are proposed,the stress and deformation of the faced rockfill dam are analyzed,the optimal parameter scheme is determined,and the stress and deformation of the dam during the completion period and the water storage period are obtained.The analysis results have certain reference value for engineering design optimization,similar engineering reference and engineering safety assurance.
