摘　　要：冬暖夏凉的被动式窑洞具有重要的研究价值。按窑顶形状可分为半园拱、割园拱、二心园拱等 ,本文通过对窑顶稳态导热的数值研究 ,得出不同位置、形状窑顶在内表面处于一。Cave house,a kind of passive system,which is warm in winter and cool in summer,has very important research value. This paper,through the numerical research of steady conduction on the arch roof,deduces the non-dimensional formulae of the conductive shape factor and overall coefficient of different shape and position of various types of cave house under the first kind and the third kind of boundary condition.
