The seepage of the fractured rock mass in dam foundations involves complex fluid‐structure coupling behavior, due to practical hydrogeological conditions. In this work, characteristics and their correlations with structural permeable mediums are experimentally explored reveal cracking effect on hydromechanical properties firstly. Subsequently, tangential compression creep damage constitutive models are, respectively, established by introducing a nonlinear viscoplastic body improve Nishihara...
According to the problems of nonlinearity and non-norm on dam displacement prediction, mode based improved ant colony algorithm-neural networks was proposed. The binary algorithm has been brought into optimization weights in Neural Networks. So that shortcomings using combinatorial continuous field have overcome, while embarrassment BP being vulnerable local optimum avoided. Therefore, this can both rapid global convergence ability algorithms extensive mapping neural networks. model new is...
The safety of water quantity and quality caused by large-scale blackwater in reservoirs with Eucalyptus plantation is currently a point great interest. largely planted southern China, especially Nanning, Guangxi, where more than 90% the drinking source are surrounded Eucalyptus, different degrees often occur many reservoirs. Recent research has demonstrated that reservoir sediments play an important role migration transformation Fe2+, Mn2+, S2-, dissolved organic carbon (DOC) overlying...
Taken gravity dam deformation as random variables, multi-scale manifestation has been taken on to build statistical model based system theory. Then monitoring transformed integrate information in the domain. Furthermore, multi scale fusion estimation established. At last, predicating of built with EWKHEFA algorithm using standardized Kalman filter. These methods have applied into an actual project and result shows that can be used prediction effectively.
Yttria partially stabilized zirconia sprayed by the air-plasma-spraying method is widely used to protect superalloy substrates due its unique thermomechanical properties, but formation and development of thermally grown oxide (TGO) often causes crack propagation in thermal barrier coatings leads accidents. In this paper, effects thickness TGO layer porosity on heat insulation properties surface residual stress between ceramic TBCs fabricated atmospheric plasma spraying were studied. Finite...
Adsorption behavior of naphthalene onto loess soil was investigated based on adsorption kinetic and isothermal experiments. The saturated capacity from Lanzhou (LZ) higher than those Jiayuguan (JYG). properties have an obvious influence soil. equilibrium reached within 24h, the kinetics well described by pseudo-second-order model, also followed intraparticle diffusion model. processes were controlled external liquid film diffusion, surface adsorption, intra-particle etc. Besides, data fitted...
The Sichuan-Tibet Railway passed through high-altitude metamorphic rock areas in western Sichuan, where freeze-thaw weathered intensely and geological disasters occured frequently, it was of great theoretical significance engineering value to carry out cycle tests on typical rocks. sandstone samples collected from the Lancang River Basin were divided into five groups, each group experienced freezing thawing about 8h(4 h 4 thawing) wide temperature range whose -40 °C 50 °. During experiment,...
