Predicting Model of Safe Distance between Tunnel and Karst Cave

Article Preview

Abstract:

A method of predicting safe distance between tunnel and karst cave based on support vector machine was proposed, 10 parameters (rock density,elasticity modulus E, poisson ratio, friction angle, cohesion C, lateral pressure coefficient , the karst cave span L,rate between height and span of the Karst cave R, tunnel deep H,cave position) were chosen for safe distance influence factors, then an intelligent predicting model of safe distance between tunnel and karst cave was built, this predicting model can predict 7 kinds position of safe distance between tunnel and concealed karst cave and was feasible and high prediction precision, which was verified by engineering example.
