| Abstract: | This paper calculated the winding rebounded reforming and analyzed the winding stress of ached roof on the condition of both symmetrical load and dissymmetrical load and calculated the critical pressure load and the critical pressure on the effort of symmetrical load. The result showed that the bigger the roof's span is, the bigger the becoming deformed of winding is. The bigger winding stress raised by dissymmetrical load is the perilous condition. The violation of the arched roof is not because of the shortage of intensity but because of the loss of stability. |
