| Abstract: | Water and unloading are important influenctial factors in fractured rock slope stability. The mechanical and physicochemical action of water on rock slope is researched. Based on elastoplastic mechanics and fracture mechanics theory; the joint growing mechanism of the slope rock under the action of compression and shearing is analyzed. The mechanism of the crack growth and propagation under the action of unloading is put forward. |
