中文摘要：
下沉式窑洞作为我国的生土建筑,具有冬暖夏凉的特性,是黄土高原上居民取得住房最方便和最经济的手段之一,在提倡生态低碳的当今,继承和发展下沉式窑洞显得格外重要,因此研究其结构的变形分析具有重要意义。通过有限元分析的方法,对下沉式窑洞结构的变形特性进行分析,并在分析比较UH模型与Mohr-Coulomb模型计算结果的基础上,说明UH模型分析下沉式窑洞结构的变形更加合适,最后使用UH模型分析下沉式窑洞在自重作用下的变形特征,得出下沉式窑洞变形的薄弱位置。
英文摘要：
Sunken cave, which is warm in winter and cool in summer, is Chinese earth construction. Cave is the most convenient and cheapest living pattern for people on Loess Plateau. It is particularly important to inherit and develop sunken cave nowadays when low carbon is highly promoted. So it is meaningful to study the deformation analysis of structure of sunken cave. In this paper, finite element method was adopted to analyze the deformation of structure of sunken cave and explained that the UH model was more suitable in the analysis. At last, the deformation characteristics was draw, and the weakest Dart of sunken caves was found out.
