摘要
针对工程实践中仍将连拱式深基坑支护结构简化为平面结构计算,其计算理论仍需完善的研究现状,提出了一种用于计算连拱式组合结构的方法。先将连拱式组合结构简化为一无铰拱,计算出组合结构中的受力大的部分,再通过增量计算法来计算组合结构中受力较大部分的内力和变形,这种方法更能符合工程的实际情况。
Aimed at multi - arch supporting structure for deep foundation pit is simplified as plane structure in practice and the calculations theory need to be improved, This paper proposes a calculation method for multi - arch composite structure. Firstly, it calculates the heavy stress part of composite structure after the multi -arch composite structure is simplified as hingeless arch. Second, it analyzes the internal force and deformation of the heavy stress part through the incremental calculation method. The results indicate that this method is more accordant with the actual situation in engineering.
