To examine the influence of cohesion and internal friction angle on surrounding rock pressure of shallow-buried and asymmetrical load tunnel under variable slopes, the thrusts on both deep and shallow sides of shallow-buried and asymmetrical load tunnel under variable slopes are obtained using limit equilibrium theory, and then the calculation methods are derived for surrounding rock pressure under variable slopes independently consider? ing cohesion and internal friction angle. The rationality of the proposed calculation methods in this paper is verified by comparison with the normative formula and existing literature. The influencing factors on the horizontal lateral pressure coefficient of the deeply buried side of the tunnel are discussed. The results show that the horizontal lateral pressure coefficient increases with the increase of the slope of the ground surface, decreases and then increases with the increase of the angle of the rock-soil, and decreases with the increase of the cohesion and internal friction angle. Besides, the split calculation of the cohesion is helpful to consider the adverse effects of the rapid changes of the me? chanical parameters (cohesion) of rock soil caused by environmental factors (such as rainfall). The internal friction angle has a greater influence on the horizontal lateral pressure coefficient of the deeply buried side of the tunnel, which shows that the split calculation of the internal friction angle is of great significance to the calculation of sur? rounding rock pressure. The relevant research results can provide a theoretical basis for the structural design of simi? lar shallow-buried and asymmetrical pressure tunnels under variable slopes.
