在桥梁电算过程中提出了一种吊杆力张拉值的拟合方法，经过若干次的调整使得吊杆张拉力逐渐接近设计目标值，该方法其实是根据给定吊杆力目标值和实际maidas计算值反算的差值。反加在按照该模型吊杆所需输入的张拉值上，如此反复迭代多次直至全桥各吊杆索力实测值与目标值相吻合，线形也与设计值接近，其他类似拱桥也可运用此方法。“,”Put forward a tensile force fitting method, In the process of the bridge Computing tension value, After several adjustments makes Suspenders Tension gradually close to the design target value,This method is in fact based on the given the Inverse of difference the boom force target value and the actual maidas value ,then Add-back tension value in accordance with the required input to the model boom,This iterative multiple not stop until the full-bridge suspender force measured value match the target value and Alignment is also close to the design values,Other the similar arch bridge also can use this method.
