The numerical analysis of aforementioned landslide during tunneling is also implemented for investigating the cause of landslide during tunneling using ABAQUS software [9], the numerical model of which is shown in aforementioned Fig. 1. The longitudinal calculation range of the numerical model is 229.4 m, and the vertical calculation ranges of both lateral sides are 111.6 m and 20 m respectively, including vertical range of 17.6 m from tunnel bottom to the lower boundary. Moreover, some

This paper presents a case study of landslide during tunneling period in hilly topography, and a practical treating countermeasure is also proposed in the study. The field investigation and numerical analysis demonstrate that tunneling in hilly topography with sloping stratification has risk of landslide while heavy rainfall permeates into ground, and a treating countermeasure of anti-slide piles combined with in-layer compacted backfilling is adopted in the practical implementation. Moreover, the implemented treating work demonstrates that the employed countermeasure is capable of treating la...
