摘要
文章首先对地基承载力规范公式P1/4进行推导,然后运用弹塑性理论对该规范公式进行对比分析,得出了一些有益的结论.证明了常规地基承载力计算公式P1/4的相当保守性,并用该公式确定了地基承载力造成的地基承载力资源的损失,这对实际工程的造价也造成了巨大的浪费.最后通过一个工程实例说明了常规公式的保守之处,并指出运用弹塑性理论计算地基承载力能充分利用地基承载力强度,解决实际工程的难题.
This paper made a deduction on and an elasto-plastic analysis about the design code formula P1/4 of the subgrade bearing capacity, from which we could obtain some useful conclusions. An example was presented to reflect the limitation of the design code formula P1/4. Also the example proved that we can make full use of the subgrade bearing capacity if we calculate it by elasto-plastic theory.
