| 1 | Application of numerical modeling and genetic programming to estimate rock mass modulus of deformation显示文摘Estimation of the rock mass modulus of deformation(Em)is one of the most important design parameters in designing many structures in and on rock.This parameter can be obtained by in situ tests,empirical relations between deformation modulus and rock mass classifcation,and estimating from laboratory tests results.In this paper,a back analysis calculation is performed to present an equation for estimation of the rock mass modulus of deformation using genetic programming(GP)and numerical modeling.A database of 40,960 datasets,including vertical stress(rz),horizontal to vertical stresses ratio(k),Poisson’s ratio(m),radius of circular tunnel(r)and wall displacement of circular tunnel on the horizontal diameter(d)for input parameters and modulus of deformation for output,was established.The selected parameters are easy to determine and rock mass modulus of deformation can be obtained from instrumentation data of any size circular galleries.The resulting RMSE of 0.86 and correlation coeffcient of97%of the proposed equation demonstrated the capability of the computer program(CP)generated by GP. | Ebrahim Ghotbi Ravandi Reza Rahmannejad Amir Ehsan Feili Monfared Esmaeil Ghotbi Ravandi | 2013 | International Journal of Mining Science and Technology2013，23，5： | 5 |

| 18 | Nickel doped zinc oxide nanoparticles produced by hydrothermal decomposition of nickel-doped zinc hydroxide nitrate显示文摘Zinc hydroxide nitrate,an anionic exchanger layered material,undoped as well as doped with 2-10% nickel,was synthesized by using a pH-controlled precipitation method.The layered materials were then used to produce the undoped and nickel-doped zinc oxides by hydrothermal-treatment.X-ray diffraction, Fourier transform infrared spectroscopy and scanning electron microscopy confirmed the formation of pure phase undoped and nickel-doped layered materials,as well as the products of the hydrothermaltreated materials,nanostructured zinc oxides.Optical studies of the nanostructured zinc oxides showed a decrease in band gap with increasing content of the doping agent,nickel. | Mohammad Yeganeh Ghotbi | 2012 | Particuology2012，10，4： | 1 |
