摘要
根据连续刚构桥主墩受力特点,找出顺桥向双薄壁墩(实心和空心)的柔性所需的宽度b;在主梁悬臂施工中产生的不平衡弯矩所需两薄壁墩抗弯刚度的两墩间距H。其计算公式简单、可靠并附计算示例,为连续刚构桥尺寸拟定时作参考。
According to the mechanical traits of the continuous rigid frame,the width of the double thin-wall pier(b)in flat direction is deduced to satisfy the flexibility;the spacing of the double thin-wall pier(H)derived from unbalanced moment in construction is deduced.The simple and creditable formulas and the illustrations can be taken as reference in dimension designs.
