摘要
土坝多因地质、地形条件复杂,施工质量难以控制等方面的影响,导致土坝应力发生变化,使坝体出现安全隐患。本文通过董封水库土坝的应力应变分析,了解到坝体局部产生不均匀变形的主要因素。通过改善坝体的应力状态和采取坝体加固措施,解决了坝体变形,达到除险加固的目的。
The main factors causing the dam body to produce the partial non-uniform deformation are understood through the stress and strain analysis of the earth dam of Dongfeng Reservoir in this paper,the consolidation measures of the dam body are given to improve the stress condition of the dam body.further to reach the purpose of removing the damger strengthening.
