以多跨连续梁为研究对象，对多个临时支撑的卸载过程进行研究，考虑卸载的非线性和时变性，假定各种不同的卸载次序，分析和比较不同的卸载次序对结构和临时支撑施工内力的影响，探讨其中的规律并提出了一些相对合理、可供参考的卸载次序和原则。最后，以国内某大跨网架的外部围护结构作为案例分析对象，应用前面分析得出的结论，确定了结构卸载的大致方案和原则。

Based on multi-span continuous beam, this paper studies on the unloading process of several temporary supports, considers the nonlinear and time variation of unloading,assumes all different load-relieving sequences, analyzes the effect of different unloading sequences on construction internal force of structure and temporary support, discusses on the law and puts forward some relatively reasonable unloading sequences and principles. Finally, with certain long-span grid of the external retaining structure as the object of case analysis, the conclusions by application of the preceding analysis determine the structure unloading plan and principle roughly.
