Study and application of nonlinear elastic-harden contact constitutive model to disturbed belt

JIN Changyu1,ZHANG Chunsheng2,FENG Xiating1(1.Research Center for Safe Deep Mining,Northeastern University,Shenyang 110819; 2.East China Hydropower Investigation and Design Institute,CHECC,Hangzhou 310014)  
An interlamination disturbed belt runs through the underground caverns of Baihetan hydropower station,characterized with low-angle dip and perfoliate formation developed from various tops of tuff.In fact,it is a disturbed shear zone of blended cataclasite and mudstone,etc.under complicated geological processes.As such formation process and internal structure are relatively complicated,the mechanical behaviors are generally difficult to describe.To reveal the structure behaviors more intuitively and reasonably,this paper,using the two-body theory,considers a sandwich biscuit element with its mutual-contacting upper and lower layers and a weak belt clamped in the interlayer,and develops a nonlinear elastic-harden contact constitutive model for this structure based on the field test data.Then,we study this contact element,search and judge it automatically with the INTERFACE element and FISH language of FLAC3D,so that the parameters for calculation of its shear stiffness and friction angle can be regulated dynamically.The coefficients Ks and φ are analyzed with a neural network technique for regression of the field test data.Comparison with the field data shows that this model better reflects the mechanical properties of the contact interface.The model was applied to the Baihetan hydropower station for stability analysis of the adjacent rock of its underground caverns,and also for quantitative evaluation of the stability of the disturbed belt based on the dynamical safety parameters.
