摘要:
为全面探讨生土地坑窑民居的结构性能,掌握以“减法法则”成型结构的整体受力变形规律,采用非线性有限元分析程序ABAQUS对生土地坑窑结构进行整体建模,并根据实际开挖成型过程进行分步分析,得到了生土地坑窑的初始应力场,探讨了各级开挖卸载下的应力、位移及塑性区的发展变化。研究成果为探讨生土地坑窑兴而不衰、屹立百年甚至数百年而不坍塌的结构奥秘及研究在役生土地坑窑结构安全性和可靠性等提供了科学依据。
Abstract:
In order to fully approach its structural property and master the deformation regularity of whole stressing for “subtraction law” shaping structure, authors used a nonlinear finite element analysis program ABAQUS to establish a whole model for underground cave dwelling and conducted a step-by-step analysis according to a practical digging and shaping process and obtained its initial stress field and discussed its development and change of stress, displacement and plastic ranges in each step of digging and downloading. The research result of the paper has supplied a scientific basis for exploring the structural secret in which underground cave dwellings have survived for a hundred or even several hundred years without collapse and studying the structural safety and reliability of underground cave dwellings in service.
