Abstract In this paper, a hydro-thermo-mechanical coupling model based on the smoothed particle hydrodynamics with total Lagrangian formula (HTM-TLF-SPH) is proposed to simulate crack propagation and instability process of fractured rock mass. TLF-SPH uses kernel approximation, that is, function its gradient need only be calculated once in initial configuration, which much more efficient than (SPH) Euler approximation. TLF-SPH, particles interact each other through virtual link, path mass...
A seepage model based on smoothed particle hydrodynamics (SPH) was developed for the simulation of pore water in porous rock mass media. Then, effectiveness proved by a two-dimensional benchmark example. Under framework SPH total Lagrangian formula, an extended hydro-mechanical coupling (EHM-TLF-SPH) proposed to simulate crack propagation and coalescence process samples with prefabricated flaws under hydraulic compressive loads. In program, kernel used approximate equations motion particles....
The seismic fragility of water supply networks is an important research component for lifeline engineering in earthquake-prone regions. An accurate computational model was established to rapidly and efficiently assess pipeline damage under excitation. In this study, the network deduced based on Copula function technology series-parallel model. This solves low accuracy problem caused by simplifying elbow, tee, other nodes ignores correlation between connected components calculation buried...
Transient ground displacement (TGD) that is caused by earthquakes can damage underground pipes. This especially critical for the joints, elbows and tees of pipes which play an important role in operation a pipe network. In this study, scale network with both tees, as well some components only or elbows, has been investigated. The response nodes network, when installed non-uniform geology, was analyzed using shaking table test ABAQUS finite element simulation. paper firstly introduced...
The construction of high-speed railways in cold regions needs to consider the effects freeze–thaw cycles (FTHs) on long-term deformation subgrades. However, at present, research creep characteristics frozen–thawed rocks and soils is not extensive. In limited studies soil properties, current focuses more high stress–strain–time responses, but for subgrades, inner stress usually low. This paper presents results triaxial compression tests remolded, silty clay sampled Yichun-Tieli area describes...
In order to optimize and upgrade the pressure releasing effect of blasting breaking hard roof, influence factors it was analyzed by theoretical analysis, numerical simulation field practice.Firstly, impact on charge structure (charge uncoupling coefficient K, axial l e radius r b ) indexes fracture zone crush radius.Secondly, evolution trend different parameters (angle hole, length hole explosive charge) studied simulation.Results show that improves obviously with increase charge.Reducing K...
Numerous researchers of soil creep behavior adopt stepwise loading (SL) rather than respective (RL) to perform the triaxial tests. However, a complete continuous strain–time curve SL needs be converted into assumed clusters supposing obtained under RL before deformation data are used develop constitutive models. Classical methods realize conversion mainly by focusing on parts and classifying them linear nonlinear compositions. Mostly, simply superposed while complex consider so neglected....
