A constitutive model based on the Johnson–Cook material and extended Drucker–Prager strength criterion was implemented in LS-DYNA to simulate rock failure process induced by a single disk cutter of tunnel boring machine. The normal, rolling, side forces were determined numerical tests. simulation results showed that normal rolling increased with increasing penetration while force changed little. also under conditions confining pressures. damage region cutting obtained two cutters acting...
In the evaluation and prediction of slope stability, traditional numerical analysis method, which is over reliant on experience, takes a large amount computing time lacks ability to reflect fuzzy nonlinear characteristics parameters well. Considering above characteristics, this study proposes an improved particle swarm optimization support vector machine (IPSO-SVM) algorithm model, combines optimized (IPSO) (SVM) applies it stability prediction. Based 28 groups engineering data, results...
With the implementation of Xiongan New Area and urbanization construction plan surrounding Beijing-Tianjin satellite, it is urgent to study apply sponge-permeable paving materials solve “urban waterlogging heat island effect.” In this paper, hydration microscopic characteristics cementitious are analyzed by means differential scanning calorimetry (DSC) test. The test water-cement ratio, porosity, gradation structure on strength permeability coefficient emphasized, change rule porous...
This paper attempts to disclose the ductility of polyvinyl alcohol (PVA) fibre reinforced concrete frame joints.For this purpose, low-cycle repeated load test was performed on four pieces joints scale 1:2, and effect PVA dosage seismic behaviour analysed.Next, were compared with ordinary in terms failure modes, hysteresis properties, energy dissipation.The results show that had much higher crack resistance, more robust curve greater dissipation than joints.Within a certain range, increased...
Based on an example of a project in Tangshan, the high-rise buildings are built karst area and mined out affected which is treated by high pressure grouting, foundation adopted form pile raft foundation. By long-term measured settlement buildings, It found that linear increase with load before building roof-sealed, increases slowly after curve tends to converge, consolidation completed. The about 80% - 84% total roof-sealed.Three layer BP neural network model used predict area.Compared data,...
The traditional PVA-ECC mix proportion is improved based on the orthogonal test to obtain PVA fiber concrete material with lesser content and conventional aggregate size satisfying structure use requirements lower construction cost requirements. Moreover, property of this conducted, failure mode piece influence factors are analyzed. Then rupture strength, compressive strength respective load-deformation curves obtained, a basis for numerical simulation provided.
