摘要

根据岩土材料Merchant、Bergers和Butterfield蠕变模型的基本形式，建立3种预测混凝土面板堆石坝蠕变沉降经验模型。以蒲石河混凝土面板堆石坝为例，采用非线性有限元方法数值模拟堆石坝的顺序填筑过程。根据堆石坝沉降现场观测数据，采用回归分析方法确定3种沉降经验模型中的待定参数，确定堆石坝的蠕变沉降随时间的变化关系。工程实践应用结果表明，所提出的堆石坝蠕变沉降经验模型具有较高的拟合和预测精度，堆石坝的蠕变沉降除与时间有关之外，还与观测点的应力状态和位置以及堆石料的变形模量有关。

Abstract

Based on the basic characteristics of Merchant

Bergers and Butterfield creep models

three kinds of empirical models for predicting creep settlements of concrete-faced rockfill dam are proposed. Taking Pushihe concrete-faced rockfill dam for example

the sequential placement processes of concrete-faced rockfill dam are simulated by using nonlinear finite element method. The empirical model parameters are determined by using regression analysis procedure according to observed data of creep settlements in-situ. The relationships between creep settlements and times are presented. The engineering practical applications show that the fitting settlements agree well with observed values. The creep settlements of concrete-faced rockfill dam are related to not only times

but also stress state

location and elastic modulus of observing points.
