A deeper understanding of interaction dynamics between hydraulic and natural fractures remains essential, especially for finite-scale fractures. In this paper, a three-dimensional fracturing model is developed by using the discrete lattice method, which can simulate meticulously dynamic evolution both to offer precise portrayal their progression. The results show that often interact with in three distinct ways: bypassing, detour crossing, crossing. Additionally, shorter distances...
Thermally-induced changes in the fracture properties of geological reservoir rocks can influence their stability, transport characteristics, and performance related to various deep subsurface energy projects. The modified maximum tangential stress (MMTS) criterion is a classical theory for predicting instability rocks. However, there lack research on accuracy MMTS when are subjected different temperatures. In this study, mechanical theoretical analysis failure mechanics experiments granite...
As high-speed trains operate at a higher speed, the problem of rail wear is more serious. In this paper, new Gaussian function correction (GFC) method proposed to design profile, two parameters are introduced control removal area. Then train vehicle dynamic model established, Kriging surrogate (KSM) used reduce number simulations and Non dominated sorting genetic algorithm-II (NSGA-II) algorithm optimize profile. Finally, characteristics wheel/rail evolution optimized profile analyzed. The...
With the expansion of urbanisation, more and metro vehicles shuttle on dedicated railway lines, leading to serious wheel wear reduced passenger comfort, it is therefore interest design a profile that matches well with lines. This paper presents optimisation procedure consists 3 steps. Firstly, taking LM profile, which widely used in China vehicles, as an example, rotary-scaling fine-tuning (RSFT) method introduced generate large number candidate profiles. Secondly, quickly reliably establish...
Aiming at the shortcomings of BP neural network in practical applications, such as easy to fall into local extremum and slow convergence speed, we optimized initial weights thresholds using particle swarm optimization (PSO). Additionally, cloud computing service, web technology, database numerical simulation were integrated construct an intelligent feedback analysis program for underground engineering safety monitoring based on PSO-BP algorithm. The could conveniently, quickly, intelligently...
Abstract Track irregularity from rail alternate side wear is manifested as uneven waveforms alternating in the left and right rails with equal intervals, which will cause carbody sway behaviour of railway vehicles greatly influences passenger comfort. In this work, mechanism due to track possible solutions issue were studied by field testing numerical calculation approaches. First, an urban transit train introduced full-scale tests, through characterized formatted are presented. Then,...
