Abstract The dynamic behavior of calcareous sand at high strain rates (HSRs), which is relevant to mining industry, aircraft wheel loading, and pile driving, still not fully understood. To investigate the effects moisture content, 34 HSR tests 26 low rate (LSR) were conducted on silica sands using split Hopkinson pressure bar (SHPB) technique with a ranging between 100 s−1 104 mechanical testing simulation (MTS) apparatus 10−5 10−1 s−1, respectively. It found that compression unsaturated...
Transparent media and particle image velocimetry (PIV) approaches were employed to measure the buckling deformation of fully embedded model piles consequent soil under different constraints in a nonintrusive manner. (also called transparent soils) are made fused quartz pore solution, refractive index which is matched with that quartz. A laser light sheet was irradiate transport capture digital images piles, PIV used obtain pile foundation mass. The results show effect constraint mode at tip...
Damage and failure of concrete structures are essentially caused by crack initialization expansion. Conventional ultrasonic tests cannot detect changes in the micro-cracks concrete. Second harmonic generation (SHG) is effective at characterizing micro-damage. However, research on influence nonlinear parameter β still insufficient. Three cubic specimens 150 mm× mm were fabricated, design average compressive strength 30 MPa 39.24 MPa, respectively. Before loading, integrity was verified using...
Anchorage failure of a suction anchor is more likely to occur in low-strength muddy clay. This paper focuses on the behaviors anchors and clay stress responses. The centrifugal model test was used study loading processes with various pulling angles. Firstly, multi-stage developing process anchoring force analyzed according results. Numerical modeling validate displacement soil were using numerical Then, testing results compared analyze horizontal pressure responses around anchors. It found...
Abstract The cement solidification/stabilization method of heavy metal contaminated soils has been promoted in engineering practice and applied on a large scale for site remediation, but it still reveals some scientific problems the current complex variable global extreme climate. To solve these explore cement-based soil remediation technology, this study used waste soda residue produced quantities "ammonia-soda process" as composite additive, established an innovative model by adding...
Based on National Engineering Laboratory for Harbor Structure-Geotechnical Centrifuge construction project, the dynamical response of piles foundation under horizontal-rocking vibration was analyzed by using finite element software Abaqus, and displacement stress characteristics were discussed with soil between reinforced high pressure jet piles. The result indicates that in operation centrifuge, changes vertical load center pile are very small; head is increasing, no longer changed until...
A large number of soft clay layers are distributed in coastal areas, which brings risks to port construction. Especially the course channel excavation, construction will affect overall stability outer riprap breakwater. Through numerical simulation and Geocentrifuge model test, influence waterway excavation on anti-sliding a breakwater Tianjin harbour is studied analyzed. The experimental results show that when boundary line 38.9 m away from foot depth 10 m, less affected. vertical...
