【摘要】 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。更多还原

【Abstract】 Sunken cave dwelling is a kind of unique residential architecture in our country,and its mechanical properties have been few in-depth study and discussion.In this paper,the data measured in practice will be used for to explore the important designed dimensions of the sunken cave dwelling.With the result of field research and finite element simulation,influences on the stress of cave-arch structure by changing the shape of arch curve and layer thickness of the main cave are studied.In further the practicability and rationality of designed dimensions in practice are explained.By the study on mechanical properties for sunken cave dwelling,not only a theoretical basis for the reinforcement and the maintenance of existing cave dwelling is built but the base of research on reliability computing is provided.更多还原
