摘 要: 分析底板合拢束产生底板横向应力的作用机理,同时选定设置横隔板与否、底板厚度以及底板线形次数作为结构参数进行参数化分析。以某主跨为170 m的连续梁桥为分析对象,结果表明,在跨中增设横隔板、增加底板厚度以及改善底板线形均能改善底板横向应力状况,但以底板线形的改善效果最为明显。

Abstract: In this paper, the mechanism of producing transverse effect from bottom continuity tendon was investigated. At the same time, this paper selected installation with or without diaphragm plate, the thickness of bottom slab, the longitudinal line shape of bottom slab as structure parameters and conducted paramatric analysis. By analyzing a main span of 170 m continuous beam bridge, the result showed that installing with diaphragm plate, increasing the thickness of bottom slab and improving the longitudinal line shape of bottom slab could ameliorate the transverse stress in bottom slab, however, the effect of improving the longitudinal line shape was most obvious.
Key words: civil engineering design; road engineering; transverse effect; parametric analysis
