用土的弹塑性模型计算扩底墩承载力

The Calculation of Bearing Capacity of a Pier by Using Elasto-Plastic Model of Soil

本文按黄文熙建议的弹塑性模型,用有限单元法计算扩底墩荷载与沉降的关系,并与扩底墩模型载荷试验结果进行了对比,分析了地基土的应力、变形分布规律及扩底墩地基土的破坏过程。初步验证了本文的计算方法。

According to the elasto-plastic model proposed by Prof. Huang Wenxi the relationship between load and settlement of a pier is calculated by using finite element method in this paper. The result thus calculated is compared with the result of a loading test from the pier model Stress, law of deformation distribution and failure procedure of the foundation soil of a pier are analyzed. The method of calculation mentioned in this paper has been verified initially.
