Influence of Lateral Earth Pressure Coefficient at Rest on Ground Displacement to Tunneling
The influences of lateral earth pressure coefficient at rest 0 on ground displacement around tunneling were researched, through using three-dimensional numerical simulation method. Some conclusions can be drawn: just because ground displacements and stratum displacements caused by tunneling have threedimensional, diachronic and regional, and are also affected by soil disorder of front opening face, closing of construction space and infusing slurry in tunneling tail, so the results arrived through three-dimensional numerical simulation method are the most reasonable. The curve of landscape orientation ground subsidence can be good reflected by Peck method and modified Peck method, but comparing with the prediction values of FLAC3D, the maximum subsidence prediction values arrived by Peck method are larger than that of FLAC3D, and the landscape orientation ground subsidence trough is narrower than that of FLAC3D. Under the condition that other parameters are unchangeable, the maximum subsidence prediction values decrease along with increment of lateral earth pressure coefficient at rest K0, simultaneously, the landscape orientation ground subsidence trough is narrower also along with it.
