| 摘 要： | 位于软土地区及地震液化地区的连续刚构桥在设计计算时,地基系数比例系数m的取值对结构的内力及配筋有较大影响,且目前规范中对m值只规定了一个范围,没有给定具体值。文中对桩侧土的比例系数m分别取不同的值来研究其对连续刚构的内力及配筋影响。

| Abstract: | When continuous rigid frame bridge which is located in soft soil or seismic liquefaction is designed,parameter value of subgrade soil ratio coefficient m has great influence on internal force and reinforcement.Scope of subgrade soil ratio coefficient m is only specified in TB 10002.5-2005at present,no detailed data.In the paper,different parameter value of subgrade soil ratio coefficient m is used in order to analyze the influence on internal force and reinforcement. |
