摘要：
Through model tests, three different locations of the interface of the soil and rock in sandy soil tunnel were simulated. The failure processes of the face and the un-supported section were described. The initial and finial depth-width ratios were obtained. The failure features and mechanism were analyzed. The tests show that the longitudinal equilibrium arch in the un-supported section fist forms, and then the tunnel face damages. The failure surface shape approximates to logarithm spire curve, and it is the interface of the soil and rock when there is the interface of the soil and rock in front of the tunnel face. The interface of the soil and rock improves the stability and the depth-width ratios of the tunnel face and the un-supported section, especially when it is in front of the tunnel face.
