通过对Mindlin位移解沿深度方向积分,利用均布侧阻和正三角形侧阻线性集中力在弹性半空间体内的位移解。给出单桩、群桩桩端以下土层沿深度的位移衰减规律,以期得出影响桩基压缩土层厚度的关键指标,为桩基沉降的土层计算压缩厚度提供理论基础。 Through the integration of Mindlin displacement in the depth direction, the displacement solution of the linear concentrated resistance in the half-space of the elastic half-space by the uniform lateral resistance and the equilateral triangle is utilized. The displacement and attenuation regularity along the depth of the soil below the pile tip of single pile and group pile are given in order to get the key indexes that affect the thickness of the soil layer and provide the theoretical basis for the calculation of the compression thickness of soil layer.
