承压板应力影响深度分析及面积选取原则

Analysis on the Range Influence Depth of the Stress under the Bearing Plate and the Principle of the Plate Area Selection

为探索地基平板载荷试验承压板尺寸的合理选取方法,本文采用弹性理论与数值计算方法对不同形状的承压板下地基附加应力进行分析,提出承压板下应力主要影响深度范围,并依此确定承压板面积选取原则。

To search the reasonable method of selecting the bearing plate size,elastic theory and numerical analysis method are used to analyze the additional stress on the foundations of the different shapes of the bearing plate,and the range influence depth of the stress under the bearing plate is proposed. Then the principle of the plate area selection is given out.
