Abstract

With the large-scale construction of high-speed railway in Western China，the proportion of tunnels in the line is getting higher and higher. At the same time，the disease caused by landslide is more and more serious during operation. However，there is no uniform standard in the design of tunnel in landslide area in China，and there is no complete calculation theory. Therefore，this paper takes the tunnel under the orthogonal system as the object of study， and through the investigation，induction and summary of the disease characteristics of the tunnel lining in the engineering example，the corresponding engineering geological model is finally established. By using the classical soil mechanics method，the vertical component of the thrust behind the slide of the tunnel is regarded as the vertical distributed load acting on the slip zone. The additional load generated by the tunnel arch is calculated by using the method of the Boussinesq J and the horizontal component is distributed on the sliding surface as the uniformly distributed load，and the Cerruti V method is used to calculate the horizontal additional load on the side wall of the tunnel. Based on the compressive strength and the Loose circle theory of tunnel，the minimum depth of tunnel under the sliding surface is calculated. Then the model test is used to verify the method and the results show that the calculation method of the additional load is in line with the engineering practice，and can provide reference for the design of the tunnel in the landslide area.

Key words： tunnelling engineering tunnel landslide disease characteristics geological model additional load loose zone
