the Application of Attribute Load Method in Nonlinear Analysis of Pile-Soil Foundation under Lateral Load

介绍了能用于计算水平横向抗力桩反应的特征荷载法 ,该法采用量纲一的图表分析形式来特征化横向受荷桩的非线性行为。通过实例结果表明 ,该法较 p y曲线法简便 ,易于手算 ,且与实测结果能有较好吻合 ;从而为横向受力桩基础设计提供了一种简而易行的手段 ,故具有一定的工程实用性。

The attribute load method, which can predict the response of horizontally resisted pile,is introduced. The nonlinear behavior of pile is characterized by this method described by dimensionless chart forms. It is indicated that the attribute load method is not only simpler than p y curve analysis, but also well approximates the result (including lateral deflection and maximum bending moments of pile) measured in field load tests.
