基于统计模型的低水头混凝土重力坝垂直位移影响因素分析
Statistical model-based analysis on influence factors of vertical displacement of low head concrete gravity dam
摘要
Abstract
Combined with an actual case of concrete gravity dam,a statistical model of vertical displacement is established in accordance with the monitoring data of its vertical displacement obtained with various instruments in various periods,and then the modeling analysis is made on the measured data with the statistical software-Dam Data Analysis,from which the variation laws of the vertical displacement of the dam crest during various monitoring stages are discussed and analyzed.The result shows that for the low head concrete gravity dam,the temperature component is the main factor to influence the vertical displacement of the dam crest,while the water pressure component and the time-dependent component have certain influences on the vertical displacement as well,but the influences are less.The study result can be applied to dam safety monitoring and management concerned.关键词
