一、问题的提出我国铁路工程技术规范和公路桥涵设计规范,对墩台基础都允许出现较大的偏心,此时基础与地基将产生部分脱离,从而应考虑应力的重分布。对于双向偏心由于计算复杂,至今尚无简便可行的直接计算公式。矩形基础双向偏心受压是墩台基础中出现最多的受力形式,本文根据上述两规范中
First, the issue put forward China’s railway engineering specifications and design specifications of highway bridges and culverts, pier foundation may allow a greater eccentricity, foundation and foundation at this time will have a partial departure, which should consider the stress redistribution. There is no straightforward direct calculation formula for bidirectional eccentricity due to the complicated calculation. The rectangular foundation bi-directional eccentric compression is the most form of stress in the abutment foundation. According to the above two specifications
