| Zusammenfassung: | The invention discloses a karst mountainous area subway tunnel engineering disaster zoning method under multi-factor coupling. The disaster zoning method comprises the following steps: (1) collecting an investigation report of a detailed investigation stage of the subway tunnel engineering; (2) segmenting the tunnel according to the distance between a stratum rock-soil interface and a tunnel vault; (3) carrying out disaster risk evaluation and zoning map drawing on water and mud burst collapse disasters in the tunnel engineering; (4) carrying out disaster risk evaluation and partition map drawing on the ground void collapse disaster; and (5) carrying out disaster risk evaluation and partition map drawing on the ground void collapse disaster. According to the method, disaster risk evaluation and zoning are carried out on the subway tunnel engineering in the karst mountainous area under the multi-factor coupling effect, the probability of accidents in the construction process of the subway tunnel in the karst a |
