高心墙堆石坝蓄水初期裂缝成因反演分析研究
Study on the Causes of Cracks at Early Impoundment Stage of High-Core Rockfill Dams
摘要
Abstract
Dam cracking is one of the important problems faced by modern rockfill dam engineering.In the paper,based on the deformation monitoring data of a high-core rockfill dam,the finite element method was used to back analyze and predict the deformation process of the dam,and the inclination method was used to predict the scope of dam cracking and the development trend.The causes of dam cracks were studied and analyzed by combining numerical methods and measured data.The results show that the wetting and rheological effects of the upstream dam material at early impoundment stage are the main factors causing the cracks in the dam.With the development of deformation,the cracks have a tendency to develop towards the core,and will be stabilized after 3 years of operation.In order to ensure the safe operation of the dam,it is recommended to strengthen the monitoring and take measures to prevent cracks.关键词
