利用MATLAB语言编制程序求解地基弹塑性承载力pcr、p1/4,在求解过程中考虑K0≠1。该方法改正了传统地基弹塑性承载力公式推导过程中K0=1这一不符实际的假定,也改正了一些学者在K0≠1时推导地基弹塑性承载力公式过程中的缺陷,并弥补了一些公式使用的局限性,得到的地基弹塑性承载力数值解更符合工程实际。给出了土体抗剪强度参数c、φ在不同的K0下对地基临界荷载p14的影响,并讨论了K0=1-sinφ′与K0=1时分别得到的地基临界荷载p1/4之间的差别。
Using MATLAB language program to solve the foundation of the elastic-plastic bearing capacity pcr, p1 / 4, in the process of solving consider K0 ≠ 1. The method corrects the unrealistic assumption of K0 = 1 in the derivation of traditional elastic-plastic bearing capacity formula of foundation and corrects the defects of some scholars in deducing the elastic-plastic bearing capacity formula of foundation when K0 ≠ 1 and makes up for some The limitation of the use of the formula and the numerical solution of the elastic-plastic bearing capacity of foundation are more in line with the actual project. The influence of soil shear strength parameters c and φ on the critical load p14 of the foundation under different K0 is given. The critical load p1 / 4 of the foundation obtained when K0 = 1-sinφ ’and K0 = 1 is discussed The difference.
