斜拉桥塔端张拉拉索倾角修正及拉索主要参数实用计算方法

Practical Calculational Method about Obliquity Rivised of the Conduction Tubes and Main Parameters of Stays - cable When Tensioned at the Top of the Pylon of Cable - stayed Brideg

从目前广泛采用的斜拉桥拉索塔端张拉的实际情况出发,在已知塔端拉索张拉力条件下,推导拉索塔、梁端 倾角修正公式.并推导了张力分布、索型方程和有应力、无应力索长计算公式,介绍简单实用的迭代计算方法,具有 高效方便快捷的特点。

To meet the practical situation of cable tensioned at the top of the pylon, supporting the tension of the cable at the pylon is known,a revised obliquity formula of the cable at the pylon and deck is concluded,at first. The second,the tension distributing as well as the differential equation for the stay - cable are derived out,the stressed length and the nonstressed length of cable are discussed therewith. The last, a simple but practical iterative method is also introduced.
