基于数值模拟K30筑坝质量检测技术

Dam Quality Inspection Technique Based on Numerical Simulation K30

为了对黔中混凝土面板堆石坝筑坝材料填筑质量进行快速检测,基于邓肯E-B模型基本原理,通过K30法得到邓肯E-B模型参数,将结果用于对大坝工程施工有限元分析中。结果发现:采用K30法测试土石料性能(参数),建立邓肯E-B模型可迅速计算出各参数,检测填料是否满足要求,缩短了计算周期,为该方法在水利工程方面的应用提供理论参考。

To carry out rapid detection of filling quality of concrete face rock-fill dam in Guizhou,Duncan E-B model parameters are obtained by using K30 methods based on the basic principles of Duncan E-B model and the result was used for finite element analysis of dam construction.The result shows that establishing the Duncan E-B model by using K30 to test the soil properties（parameters）can detect whether fillers meet the requirements or not and shorten the calculation cycle,providing theoretical references for the application of this method in the water conservancy project.
