摘要
以赣州沙石大桥为工程实例,通过对V形支撑桥梁边界条件的改变(固结或铰接)、挂孔的设置与否和挂孔的数目及位置改变等可以将V形支撑桥梁分为全设支座连续梁、连续刚构、拱(V撑上挂孔),其中连续刚构又可细分为不设挂孔连续刚构、设一个挂孔连续刚构、设三个挂孔连续刚构、连续梁与刚构组合.通过对以上六种结构体系的对比分析,较为系统地研究出V形支撑桥梁结构的总体受力特性.
This paper was based on the Shashi Bridge of Ganzhou .By changing the boundary conditions （ consolidation or hinged ） , whether setting suspended span or not , and changing the number and location of sus-pended span , bridge with v-shaped support can be divided into full set bearing continuous beam , Continuous rigid frame and arch （ there is suspended span on the v -shaped support ） .Especially , Continuous rigid frame can be subdivided into continuous rigid frame with no suspended span , continuous rigid frame with one suspen-ded span , continuous rigid frame with three suspended spans , and the combination of rigid frame and continuous beam .By comparing the above analysis of the six structural system , the overall mechanical characteristics of the bridge with v-shaped support was developed systematically .
