从斜撑系统的协同变形理论出发,利用最小势能解,提出了分区段先拆后撑的思路,推导了该类支撑结构在分段拆撑过程中,拆撑区段长度的计算方法。并结合具体工程实例,对该计算理论和结果加以验证,证实该方法是可行的,从而可以为今后该类支护形式的拆撑设计和施工提供借鉴。 Based on the synergetic deformation theory of the bracing system, the idea of ​​the first support and the second support after the section is proposed by using the minimum potential energy solution, and the calculation method of the length of the support and support section during the process of the section support is deduced. Combined with the concrete engineering examples, the calculation theory and the results are verified, which proves that the method is feasible, which can provide reference for the design and construction of the bracing system in the future.
