计算地基应力与基础沉降的方感应图

本文将纽马克(Newmark)等人的二张圆形感应图(应力感应图与变形感应图)改为一张方形感应图,用应力感应值表来计算地基不同深度的附加应力,用变形感应值表来计算均质和非均质地基的沉降。 文中还讨论了相邻基础或荷载在水平方向需考虑的影响范围及压缩层厚度的核算方法。

Square Influence Chart for Computing Stresses in Subsoil and Settlement of Foundation

In this paper, two circular influence charts(the stress influence chart and the deformation influence chart) made by Newmark et al. have been transformed into a square influence chart The additional stresses in subsoil at different depths can be computed by using the stress influence value table and the settlement of foundafion on the uniform and nonuniform subsoil strata can be computed by the deformation influence value table.The effecting range in the horizontal direction due to the adjacent foundations and loads which ought to be considered, and the method for checking the thickness of the compressible stratum are also discussed in this paper.
