On Confirmation of Suspender Tensile Force during Construction Control of Self-anchored Suspension Bridge

自锚式悬索桥施工过程中,控制吊杆施工张拉力,使桥梁在施工完毕后达到理想的设计状态,是个非常重要的工作。结合自锚式悬索桥施工过程中的力学特性,提出了基于几何线性、几何非线性的影响矩阵法确定自锚式悬索桥的施工张拉力。该方法计算简单,所得结果符合要求。

It is very important of controlling suspender tensile force during self-anchored suspension bridge construction process to make the bridge arrive at ideal design state after the completion.Combined with mechanics characteristics during the construction process,the influence matrix based on geometrical linear & non-linear is proposed to confirm the construction tensile force of self-anchored suspension bridge.The research can show that the method is of simple calculation and the results can meet with the requirements.
