双柱式墩台活载内力的简便计算方法

The Simple Calculation of Live Load Internal Force in the Pier and Abutment with Double Pile

本文分析了桩与盖梁的受力模型，总结了盖梁在车辆荷载的间接作用下，桩柱反力和盖梁内力影响线的绘制方法，推导出桩顶最大活载反力和盖梁内力的简便计算方法，该方法对桩柱式墩台的设计及其程序编写具有实用价值。

The model of bearing force of pile and cover girder is set up. Under the function of indirect vehicle load, the method drawing the influence line of the reaction of pile and internal force in cover girder is summarized, and the simple and convenient method calculating the largest the reaction of pile and internal force in cover girder is concluded. The methods are very valuable for designing and programming of the pier and abutment with double pile.
