This study presents an improved constitutive model for concrete under uniaxial cyclic loading which considers the fatigue stiffness degradation, strength and residual strain increment of damage. According to model, dynamic response cumulative damage tunnel cross structure various train operation years were analyzed. The results show that vibration in middle main is most violent. With increase period, acceleration transverse passage floor, both sides wall corner vault significantly, maximum...
The shortest simple path problem with must-pass nodes (SSPP-MPN) aims to find a minimum-cost in directed graph, where some specified must be visited. We call these as nodes. SSPP-MPN has been proven NP-hard when the number of is more than one, and it at least difficult traveling salesmen (TSP), well-known problem. In this paper, we propose multi-stage metaheuristic algorithm based on multiple strategies such k-opt move, candidate search, conflicting promotion, connectivity relaxation for...
Previous studies have performed numerical simulations of adjacent parallel shield tunnels under train-induced vibration loads. However, few experimental been for the interaction mechanisms. In this study, modeling is conduced to explore subjected different A new Hilbert-Huang transform (HHT) applied obtain instantaneous responses tunnels. The results show that acceleration tunnel follows trend train load curve. peak accelerations experience a unimodal distribution along speed, while dominant...
To study the effect of wetting-drying cycles on dynamic tensile strength rock, indirect tension test sandstone samples after 0, 1, 3, and 5 was conducted. Tensile failure observed by digital image correlation. The result shows that appears in center initially, consistent with strain field results obtained An empirical formula derived to link loading rate rock cycles. As increases, increases significantly. reduces as number increases. These provide reference data for complex engineering...
Dislocations of circumferential seams are commonly prevalent in shield tunnels. Generally, the displacement space bolt rigid segment joint is very small. When dislocation seam large, plastic deformation bolts or concrete crushing inevitable, which will affect service life tunnel. The flexibility can be achieved by embedding a dowel, reduce damage during misalignment seam. However, addition dowel changes structure joint. At present, shear bearing capacity joint, affecting design, safety...
Summary Microseismic monitoring is a conventional technique used for mapping hydraulic fracturing. Accurate locations of microseismic events are strongly dependent on an accurate velocity model. The model generally obtained by calibration from inverting perforation data. In some cases, however, perforations may only illuminate layers between the and receivers. While occur outside these layers. To derive structure covering all events, we add inversion capability into recently developed Cross...
With the continuous development and progress of power system grid connected operation high-capacity photovoltaic, wind other new energy generation, structure modern is becoming more complex. The input removal photovoltaic generation make uncertain factors increasing. traditional deterministic flow calculation method can not accurately reflect actual state current with high proportion renewable energy. In order to deal randomness brought by permeability access distribution network, this paper...
