Toppled rock body classification method

The invention provides a toppled rock body classification method. The method comprises the steps of setting seven classification indexes for evaluating toppled rock bodies, wherein the classification indexes include a deformation feature, a rock stratum tilt angle, an inter-stratum maximum extensional amount, an inter-stratum unit extensional amount, an unloading deformation feature, a weathering degree and a longitudinal wave velocity; and according to comprehensive judgment of the classification indexes, classifying the toppled rock bodies into three types: an A-type extremely strong toppled cracking region, a B-type strong toppled cracking region and a C-type weak toppled transitional deformation region. According to the method, the classification indexes can pointedly describe basic deformation cracking features of the toppled rock bodies; the field workload is small; and in the aspect of evaluating the stability of the toppled deformed rock bodies, the effect of getting twofold results with half the effo
