关于连续梁桥墩计算长度系数μ值的探讨

Study on Effective Length Factor of the Continuou Bridge Pier

桥墩的计算长度对桥墩的承载力计算有较大影响。影响计算长度系数的因素较多,论文综合考虑了桥墩高度、地基约束作用、支座约束状态以及整联桥上下部结构的相互影响,采用电算与手算相结合的方法,提出了一种较准确的计算桥墩计算长度系数μ的方法,有关经验可以供相关专业人员参考。

It is have greater influence calculate the length of the bridge pier to the bearing capacity. The factors of affect the calculated length coefficient have more, this paper comprehensive consider the highly of the bridge pier、the constraint function of the foundation、the constraint function of the bearing and impect with each other of the top and bottom structure to the bridge, using the method of the combination of computer and by hand, put forward a accurate method of the length of the coefficientμto calculate of the bridge pier,the relevant experience can provide reference to the relevant professional
