SUPERPOSITION OF MULTI-FORCE-FIELD IN KARST COLLAPSE

From the geological condition in Karst collapse occurring, different collapsing force-fields,and present different superposition modes in different geological and hydroglogy conditions,are analysed in the article .The superposition regularity and mathematical representation in the different superposition modes of multi-force-field in Karst collapse are also analysed and discussed in the article .The release coefficient of Karst collapse is also present in the article.
