2Study on distribution rule of sliding pushing force and remnant resistant sliding force acting on anti-sliding pile显示文摘Anti-slide pile is one of the important methods to administer landslide geological disaster because of its advantages.It plays important role in administering landslide.It is a premise of reasonable economy and technological advance to know the distribution rule and feature of the force between anti-sliding pile and surrounding rock.To determine the sliding force and remnant resistant sliding force,according to need of study,this paper sets up the geological model and mechanics model in term of a typical landslide,and analyzes the effect rule of sliding body distortion,strength and gravity to the pushing force and remnant resistant sliding force by use of the numerical model.The distribution rule of pushing force and remnant resistant sliding force of the type of landslide is given.Qingyang YU Lei NIE 2006Global Geology2006,9,2:1

7Elastic fields induced by non-elastic eigenstrains in a plane elliptical inhomogeneity existing in orthotropic media under uniform tension at infinity显示文摘This paper presents an analytical solution for the elastic fields induced by non-elastic eigenstrains in a plane elliptical inhomogeneity embedded in the orthotropic matrix under tension at infinity and inclined at any angle. The conformal transformation and complex function method for the anisotropic elastic material were used to determine the strain energies in the inhomogeneity and matrix, which were expressed by four undetermined coefficients characterizing the equilibrium boundary of the inhomogeneity due to the acting eigenstrains and external load. The use of the principle of the minimum potential energy led to analytical expres-sions for these coefficients and thus generated a closed-form solution for the elas-tic strain/stress fields. The resulting stress field in the inhomogeneity was exam-ined and verified by checking the continuity conditions for the normal and shear stresses on the interior boundary of the matrix.GUO Lei NIE GuoHua 2008Science China(Physics,Mechanics & Astronomy)2008,51,2:1

11The Two Techniques of O. Henry's显示文摘O.Henry is the founder of American modern short story, What makes his stories enjoy most popularity is his own styles——(1)Reasonable artistic exaggreration. (2)Unexpected ending. In this article I emphatically comment its value in the two stories: The Romance of a Busy Broker and The Last Leaf. Up to Now there is still much in Henry’s method that we can make use of beneficially.Li Lei Nie Xiao min 1999兵团教育学院学报1999,9,3:0
12Finite element analysis for blasting law of jointed rock mass显示文摘On the basis of Mises strength theory,rock models are built including vertical,horizontal and diagonal joints to simulate jointed rock mass under blasting load by using FEM. The dynamic procedures of jointed rock mass under blasting are quantified and the effective stress-time curves of typical elements are compared to analyze the barrier of joints to the stress wave. The blasting law was studied according to the process of computer simulation and the effect of blasting,and some suggestions were given for solving the problems of overbreak and underbreak.YU Qingyang NIE Lei ZHOU Nengjuan 2009Global Geology2009,12,4:0

14Wave dispersion and attenuation in viscoelastic isotropic media containing multiphase flow and its application显示文摘In this paper,we introduce the complex modulus to express the viscoelasticity of a medium.According to the correspondence principle,the Biot-Squirt(BISQ)equations in the steady-state case are presented for the space-frequency domain described by solid displacements and fluid pressure in a homogeneous viscoelastic medium.The effective bulk modulus of a multiphase flow is computed by the Voigt formula,and the characteristic squirt-flow length is revised for the gas-included case.We then build a viscoelastic BISQ model containing a multiphase flow.Through using this model,wave dispersion and attenuation are studied in a medium with low porosity and low permeability.Furthermore,this model is applied to observed interwell seismic data.Analysis of these data reveals that the viscoelastic parameter tanδ is not a constant.Thus,we present a linear frequency-dependent function in the interwell seismic frequency range to express tanδ.This improves the fit between the observed data and theoretical results.YANG Lei YANG DingHui NIE JianXin 2014Science China(Physics,Mechanics & Astronomy)2014,57,6:13

18Aging behavior of nano-SiC_p reinforced AZ61 magnesium matrix composites显示文摘The mechanical properties of magnesium matrix composties can be further improved by aging treatment. To study the aging behavior of SiC particles reinforced AZ61 magnesium matrix composites fabricated by ultrasonic method, an investigation has been undertaken by means of Vickers hardness measurement, scanning electron microscopy (SEM) and energy spectrum analyzing apparatus. The box-type heat treatment furnace was used in the study. The results showed that no discontinuous cellular precipitation is observed at the grain boundaries in the magnesium matrix of the composite while the Mg17Al12 preferentially precipitates in the matrix. The time to reach the peak hardness for AZ61 alloy or SiCp/AZ61 magnesium matrix composites is reduced with the increase of aging temperature. At the same temperature, the composite exhibit an accelerated aging manner but lower aging efficiency, compared with the unreinforced matrix alloy. The microhardness of the composite is higher than that of the unreinforced matrix alloy, because that the SiC particles distributes homogeneously in the matrix alloy under the ultrasonic processing condition.Yan Hong Hu Xiaowu Nie Qiao Chen Lei 2011China Foundry2011,8,3:2
