| Abstract: | It is very important to estimate the safety thickness of karst cave roof for karst ground reinforncement.Conditions affecting the stability of karst cave roof are analyized,premises of engineering experimental analogy and analytical methods are also summed up in detail.Taking the navigation houses of Kunming New Airport as an example,the safety thickness of karst cave roof is estimated by general analysis methods.An experimental relationship among stability,cave span and roof thickness is suggested. |
