Abstract Vertically dynamic model of a large-diameter pile in frozen soil is established, which the described to saturated porous media, and large diameter end-bearing simplified one-dimensional rod considering influence transverse inertia effect. Analytical solutions longitudinal coupling vibration between are obtained using Helmholtz decomposition variable separation methods frequency domain. By comparing responses with traditionally pile, as well impedance factor layer induced by...
The low-strain integrity testing of large-diameter piles has attracted more and attention because its wide application in offshore engineering, such as for wind turbines, etc. Body Rayleigh waves generate on the top surface after excitation load. multi-reflections these from pile side result obvious three-dimensional effect at top. Therefore, one-dimensional wave theory is no longer suitable interpreting propagation body under vertical excitation. In this paper, based “pile pile” conception,...
Abstract Based on the torsional plane strain model and tapered fictitious soil pile model, vibration characteristics of considering stress diffusion effect end is investigated theoretically. Considering coupling conditions pile-soil system, impedance at head obtained by means Laplace transform transfer method. A parametric study performed, rationality verified influence cone angle embedded in layered studied. The results show that: has obvious with shorter length.
To investigate the influences of shield tunnel construction on settlement existing pipeline, based a double-line underpass pipeline No. 3 Zhengzhou Metro Line, three-dimension numerical model was established by using FLAC3D software.The verified monitoring data and ground surface under different cases were studied.Results show that settlements simulation are consistent with measured data.When moving forward, above excavation face continue to increase.When distance away from is 24 m, no...
