| 7. | The comparisons of the results in the analysis of the ii devised program and the ansys software and the code gbj7 - 89 show that the finite numerical method used in the paper can combine the analyses of the bearing capacity and the settlement of the foundation at the same time and can obtain the nonlinear settlement of the foundation under different load grade and the development of the soil plastic zone and the ultimate bearing capacity of the foundation and can imply the practical mechanism of loaded soil below the shallow foundation under the vertical load
在两类地基情况中均对本文程序、 ansys有限元软件、规范gbj7 - 89的计算结果进行了比较，结果表明，本文的有限元数值分析方法可将地基的沉降及承载力分析结合起来，可求得各级荷载下地基的非线性沉降变形、地基土体塑性区的开展情况和地基的极限承载力，能反映竖向荷载作用下浅基础地基的实际工作机理。 |

本文即以有限元-无限元耦合的数值方法用fortran90语言编制了竖向荷载作用下浅基础地基的非线性、弹塑性三维分析程序，分析中采用的土的本构模型有非线性的邓肯-张模型、成都科大k - g模型和弹塑性的修正剑桥模型、殷宗泽双屈服面模型、 drucker - prager模型。 |
| 9. | The current chinese foundation design code gbj7 - 89 use limit equilibrium theoiy with elastic soil stress distribution to give out bearing capacity design value calculating fonnula and use elastic soil model to evaluate foundation settlement . according to the above theories , code gbj7 - 89 gives the correlative terms . but these do not accord with the practical mechanism of loaded soil below the shallow foundation and the elastoplastic property of natural soil so defects exist
我国现行规范gbj7 - 89将这两者分开考虑，其计算地基承载力设计值的公式是根据弹性地基中应力分布及土的极限平衡状态理论为依据而得出的，求地基的沉降变形时则视土体为弹性，这些理论对地基及土的假设与浅基础地基的实际工作状态及天然土体的非线性、弹塑性存在一定的偏差。 |
