摘要: 为了研究堆石坝竣工期的垂直和水平变形特性,采用ABAQUS 软件中的单元生死方法数值模拟了堆石坝的分层浇筑过程. 建立了堆石坝变形与上游水位、环境温度和时效之间的非线性关系模型. 采用多元非线性回归分析方法,根据现场观测数据确定了堆石坝变形模型中的参数. 研究表明,堆石坝沉降变形具有较好的规律性,沉降变形预测模型预测结果与现场观测值基本一致.

关键词: 混凝土面板堆石坝|变形特性|观测数据|非线性回归分析|数值模拟

Abstract: The pouring process of the Pushihe concrete-faced rockfill dam is simulated by using the ABAQUS finite element software and the element birth and death procedure. The deformation characteristics of the dam after completion of construction and the stage of full water are investigated. The mathematical models of the dam deformations versus the water level, the environmental temperature and the time-effect are proposed. Based on the in-situ observation data for the dam deformations and the multi-element and nonlinear regression analysis approach, the parameters of the mathematical models are estimated. It is indicated that the vertical deformations are quite regular and the forecasted vertical deformations of the dam are in a good agreement with observations.

Key words: concrete-faced rockfill dam|deformation characteristics|observing data|nonlinear regression analysis|numerical simulation
