摘要
本文在分析文献[1]所给简化公式存在问题的情况下,进一步改进了文献[1]所给回归简化公式的回归参数,增加了大量新的子样,得出了一套新的梁式桥墩抗震计算简化公式。新简化公式不仅适合文献[1]所给简化公式的适用范围,而且适合高桩承台、软土地基及液化地基的桩基桥墩,把它推广到沉井及浅平基的梁式桥墩使用亦有良好精度。
Based on analyzing the existing problems of the simplified formula given by the paper[1],by improving the regression parameters and increasing a large amount of subsamples,in this paper,a new regression simplified formula of the earthquake-resistant calculationfor the piers of the beam bridge has been proposed. The new simplified formula is suitablenot only for the sphere of paper[1],but also for the pile supported bridge piers with soft orliquefied bases. The applications of this new formula to the sphere of caisson foundations andshallow foundations will also have high accuracy.
