Embodiment 1
[0028] A method for calculating the maximum movement distance of a collapse in a karst area, comprising the following steps:
[0029] a. Determine the basic data of the collapse body through surveying and mapping, including the position of the crack at the back end of the collapse, the position of the front end of the collapse, the average length of the collapse and the width of the collapse, and calculate the collapse area A, in m 2 , calculate the collapse volume V by formula 1, unit m 3 ;
[0030] V=0.146A 1.332 Formula 1;
[0031] b. Measure the elevation difference H, the unit is m, and determine the maximum movement distance L of the collapse according to the elevation difference H and the collapse volume V max , unit m;
[0032] When the collapse volume V>100000m 3 When , the maximum movement distance L of the collapse max Calculated by formula 2;
[0033] L max =H / 10 -0.109log V+0.17 Formula 2;
[0034] When the collapse volume V3 When , the maximum movement...
