地坑窑作为我国一种独特的民居建筑形式,其结构力学性能一直少有学者进行深入的研究与探讨。以实测数据作为分析的依据,探讨地坑窑建造时的重要设计尺寸。依据实地调研结果构造窑拱曲线形状参数,结合有限元仿真计算,研究主窑拱顶曲线形状与覆土层厚度改变对窑拱结构受力的影响,并进一步验证建造者实践中所采用的设计尺寸在力学上的实用性与合理性。地坑窑结构力学性能的研究不仅为在役窑居的加固与维修提供理论依据,而且为其可靠性的计算提供研究基础。
As a unique form of residential architecture in our country, the pit kiln has been rarely studied and discussed by many scholars for its structural mechanics performance. Taking the measured data as the basis for the analysis, the important design dimensions of the pit kiln are discussed. According to the results of on-the-spot investigation, the shape parameters of the arch of the kiln arch were constructed, and the influence of the curve shape of the vault of the main kiln and the thickness change of the overburden on the stress of the arch structure was studied based on the finite element simulation calculation. Furthermore, the designed dimensions Practicality and rationality in mechanics. The study of the mechanics performance of the pit kiln structure not only provides the theoretical basis for the reinforcement and repair of the service kiln, but also provides the research foundation for its reliability calculation.
