SUMMARY In order to investigate the seismic failure characteristics of a structure on liquefiable ground, series shaking table tests were conducted based plaster model three‐story and three‐span subway station. The dynamic responses ground soil under main shock aftershock motions studied. sand boils waterspouts phenomena, surface cracks, earthquake‐induced settlements observed in testing. For structure, upward movement, local damage member cracking obtained. Under shock, there appeared...
Abstract A generic loosely coupled effective stress method is presented in this article for one‐, two‐ and three‐ dimensional (1D, 2D 3D) nonlinear site response analyses. In method, the 1D non‐Masing hysteretic constitutive model of Chen et al (2020) extended into 3D conditions, by presenting a clever generalized formulation equivalent shear strain ( γ eq ). The element‐level simulation tests show that proposed algorithm conceptually simple with high precision to capture reversals under...
Although the undrained anisotropic behaviour of sand has been extensively studied, little is known about anisotropy and liquefaction susceptibility silt soil. This paper presents a systematic experimental study on response soil under different patterns principal stress rotation, including 90° jump continuous rotation stress. Particular attention focused influence cyclic path ratio (CSR) pore pressure r u deviatoric strain amplitude γ qa . A remarkable finding this that, for all loading...
Ensuring the safety of undersea shield tunnels constructed in soft marine deposits that are subject to strong seismic motion represents a major engineering challenge. An example one such tunnel is 2.70 km-long subsea highway crossing under Gulf Suai Rongjiang River Estuary Shantou, China. Using generalized response displacement method, authors developed nonlinear analysis segmental lining for 2.7 tunnel. In proposed longitudinal analysis, geology characteristics and dynamic behavior seabed...
A new strain-based model is presented in this paper for assessing the residual excess pore-water pressure (ue) buildup fully saturated sands. In model, generation of ue quantified by volumetric strain changes owing to cyclic shearing. The concept threshold shear introduced into model. To characterize a number tests, including one resonant column test, series undrained and drained multistage, single-stage strain-controlled triaxial (CTX) are performed with fine sand samples. shear-volume...
A total of 153 cyclic triaxial tests were performed on 19 sand–gravel mixtures over the strain range 10–5–10–2, which shows that particle characteristics have significant influence small-strain shear-modulus G0, shear modulus reduction G/G0, and damping ratio λ. An improved Hardin's equation for G0 was proposed to consider effects consolidation state. Furthermore, KZM model correlation characterize G/G0 curve. four-parameter λ with parent rock type, gradation, condition also introduced
This paper presents a new approach to assess the liquefaction triggering of saturated sandy soils based on comprehensive laboratory datasets in conjunction with concept binary packing material for soils. The equivalent skeleton void ratio (esk*) is used as an alternative state index fines content (FC) less than threshold value (FCth). To characterize curve correlation between cyclic resistance (CRR15) 15 cycles and corrected shear-wave velocity (Vs1), series undrained triaxial tests well...
