底板有齿坎时水闸地基反力分布规律的研究

对一建在软基上底板有齿坎的水闸进行原型试验,测试不同工况下底板的地基反力,用有限元法计算相应的地基反力。通过实测值、计算值的对比分析,发现底板有齿坎时水闸地基反力分布并不均匀,地基反力在两端齿坎下相对集中。随着上部荷载的增加,地基反力分布向均匀化方向发展。

Study on Subgrade Reacting Force Distribution Rule of Sluice With Tenons Under the Foundation Mat

The subgrade reacting force in different stages through construction period is measured by in-site testing of a real sluice with tenons under the foundation mat,the corresponding subgrade reacting force is worked out by FEM(finite element method).By comparing and analysing of the observed value and computational results,it is found that the subgrade reacting force is nonuniform and concentrated under the tenons.With the increasing of the load from upper structure,subgrade reacting force inclines to be uniform.
