摘要
Abstract
In view of the lag effect and the nonlinear characteristics of the influence of upstream water level and rainfall on the uplift pressure of concrete gravity dam , a monitoring model of the concrete gravity dam considering
<br> the nonlinear environmental influence is established .The influential process is regarded as a normal distribution process and the lagging days and influential days are optimized by improved quantum genetic algorithm to raise the fitting and forecasting accuracy .Finally, a concrete gravity dam is taken as an example and the corresponding uplift pressure series of the measuring point A 6-UP-01 are fitted and predicted with the proposed method .Through com-parison between measured data and predicted data , the proposed method is verified superior to the traditional statis-tic model and it is of scientific and practical application value .关键词
