摘要:采用双剪统一强度理论,导出了太沙基地基极限承载力公式,绘出了强度理论参数 b 的影响曲线。所给出的
解可以灵活地适用于各种不同特性材料地基承载力的计算。已有的 Mohr-Coulomb 解、双剪强度理论解均为其特例。
统一解大于 Mohr-Coulomb、双剪强度理论解,它可以更好地发挥地基材料的强度潜力,工程应用可获得明显的经济
效益。

Abstract:The double-shear unified strength theory is used to derive the formula of the Terzaghi′s ultimate bearing
capacity of foundation. The influence curves of the coefficient b are drawn. The solutions given can be flexibly
used to calculate the ultimate capacity of all kinds of different special properties materials foundations. The
solutions based on Mohr-Coulomb and double-shear strength theory are all the special cases of its solutions. The
unified solutions are greater than that of the Mohr-Coulomb and
