探讨混凝土坝空间位移场的正反分析模型

ANALYSIS AND BACK ANALYSIS MODEL OF 3—D DISPLACEMENT FIELD OF CONCRETE DAMS

  • 摘要: 本文应用场论和力学分析,提出了结合实测资料,建立坝体、坝基和库盘整体的空间位移场正反分析模型的方法,以及考虑因子相关与不相关两种情况时,提出了反演坝体、坝基和库盘分区分层与整体变形参数的方法.上述理论和方法已成功地应用于龙羊峡工程,解释了该坝蓄水以来运行中出现的变形疑点的成因。

     

    Abstract: Based on the field theory and mechanical analysis,the author presents a new method to build a 3-D displacement field of dam body,dam base and the whole river-bed from analysis and back analysis model.It presents a method to feedback the partial and whole distortion parameters of the dam body,the dam base and the river-bed when ever the factors correlate or not.The above theory and method were applied in Long Yang Xia project,and it successfully explained the cause of doubtful distortion point during the dam's operational peri-od.
