摘要：

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.
