Inversion and feedback analysis of mechanical parameters of surrounding rock of relief well of Nuozhadu Hydropower Station

NIE Wei-ping1,2,YANG Yun-hao1,2,SHI Chong1,2,LIU Xing-ning3(1.Key Laboratory of Ministry of Education for Geomechanics and Embankment Engineering,Hohai University,Nanjing 210098,China;2.Geotechnical Research Institute,Hohai University,Nanjing 210098,China;3.Kunming Hydroelectric Investigation,Design and Research Institute of China Hydropower Enginering Consulting Group Co.,Kunming 650051,China)  
Based on the characteristics of project area of relief well of Nuozhadu Hydropower Station,a 3D mathematical model was established.The elastic moduli of various rock strata in the project area were inversed according to the analysis of measured displacements,the method of BP neural network and the principle of the minimum residual error.Furthermore,the inversed parameters were introduced into the model for 3D elastic-plastic feedback calculation.The inverse analysis of the measured displacements show that the crown displacement of the relief well increases with the increase of excavated quantity,the maximum displacement of 1.68 mm occurs at the connecting point of the 1st relief well and the upper chamber.The inversed elastic moduli of various rock strata are as follows: 24.11 GPa for fresh rock mass,10.13 GPa for the superstratum of slightly weathered rock mass,3.16 GPa for the substratum of slightly weathered rock mass,0.20 GPa for strongly weathered rock mass and 0.62 GPa for fault.The minimum residual is 16.82 mm2.The observed and calculated displacements and displacement increments basically have the same varation tendency,indicating that the inversed parameters are reliable.The calculated displacement is generally larger than observed one because of instantaneous unloading during actual excavation,and the largest calculated displacement is 3.22 mm.The deformation direction of surrounding rock is mainly towards the free face,the deformation is small,and the surrounding rock is relatively stable.
