前言关于桩在外力作用下受力情况的分析,已提出了种种计算方法,但在日本公路桥梁设计规范Ⅳ下部构造篇(以下简称为“规范”)中所采用的计算方法具有以下特点:1.竖向承载力的确定,系采用由整理日本进行的许多荷载试验资料所推得的经验方法。
Preface Various calculation methods have been proposed for the analysis of the forces acting on piles under external forces. However, the calculation methods used in the construction of the lower section of the Japanese Highway Bridge Design Code IV (hereinafter referred to as the “Specifications”) have the following characteristics: 1 The determination of vertical bearing capacity is based on the empirical method deduced from many load test data conducted in Japan.
