| Abstract: | Factors affecting the stability of cave roofs of Xin Jiefang bridge in Guilin city are analysied by review of previous data.The effect of all factors on the stability of cave roofs and the variability law are studied by means of the structure mechanics method on the course. The stability of the cave roofs of under the condition of both self-weight pressure and outside loading can be known. |
