摘　　要：传统生土窑洞没有栋梁支撑,完全由挖凿成型的纯原状土拱作为自支撑结构体系。它们的建造没有经过正规设计和计算,但却能够居住百年甚至数百年而不坍塌。首先通过有限元软件,模拟分析生土窑洞土拱结构体系的受力变形规律;其次,研究民间营造在役生土窑居土拱结构体系构成和主要结构参数之间的关系。通过有限元模拟计算分析结果和民间营造现状的对比,探讨了民间营造的土拱结构体系所蕴涵的结构和力学原理,从而揭示传统生土窑居土拱体系合理性、可靠性和科学性,有助于生土窑洞的保护和传承。Primitive earth-sheltered dwellings have not beam supports, and completely use a digging raw eartharched system as self-support system. Their construction has not formal design and calculation, but can allow people live for hundreds of years. This paper has firstly analyzed bearing property and deformation of structural system through finite element simulation, and then explored the relationship between earth-sheltered dwellings folk construction and main structural parameters. In comparison of finite element simulation results with that of folk construction background, feasibility, reliability and scientific value of earth-sheltered dwelling structural systems were discussed to reveal structural and mechanical principles in construction. The structure and principle can be helpful to the protection and passing-on of earth-sheltered dwelling.
