Pile foundations are vulnerable to fault deformations. However, both the physical and numerical modeling of pile under deformations complicated time-consuming. A simplified model is required for design engineering practices. This study proposed a novel analysis predict behaviors single piles subjected reverse faulting. two-dimensional beam–spring applied. The calculations stiffnesses soil springs, skin friction, ultimate resistances, Young’s modulus sand presented discussed. results show...
Abstract The potential for CO 2 sequestration in the goaf of abandoned coal mines is significant due to extensive fracture spaces and substantial residual present. Firstly, adsorption characteristics on were studied by isothermal test . Then, accurately calculate amount adsorbed within goaf, bidisperse diffusion numerical model considering only Fick was modified combination with mechanisms. simulation results showed that can well describe behavior matrix. Finally, carried out, influence...
Fault deformation can cause severe damage to structures located within the fault zones. A logarithmic spiral model was developed by D. A. Cole and P. V. Lade in 1984 predict shapes locations of ruptures sand caused dip–slip faulting, based on 1g sandbox tests. However, it shows poor predictions for reverse observed centrifuge In this study, modelling faulting performed explore reasons model. These tests were conducted free-field conditions with different densities soil thicknesses. Based...
Based on the existing numerical models of shield tunnel with double lining, an improved model is developed and its rationality verified by a similar test. In model, joint, junction surface, respectively, are simulated beam, spring, combination compression bar spring. Through comparison analysis results models, it turns out that defects or problems in resolved; tension appearance contact surface abrupt change bending moment linings solved because element coupling technology node displacement...
In this article, the influence of soil condition on dynamic response a tunnel and surrounding was studied by both experimental model tests numerical simulations. We tested 1/20‐scale with three different conditions: upper soft lower hard soil, homogeneous soil. also applied loads, sweep loads train for time domain frequency analysis. The results revealed that interface between strata has an obvious amplification effect vibration wave. With propagation wave to surface, damping above becomes...
Previous studies have found that pile foundations will be severely damaged when subjected to faulting. However, the pile–soil interaction mechanism is still unclear due lack of well-documented field observations and physical model tests. In this study, six centrifuge tests were conducted investigate single piles sand dip-slip faulting discuss some influential factors, such as fault type, location, uplift ratio, stiffness, density. The responses are sensitive ratio. Piles in a reverse...
Severe damages of structures observed in previous earthquakes due to faulting, especially reverse faulting with large discontinuous ground displacement under earth pressure, have triggered studies on the failure mechanism within fault zone. However, most centrifuge tests focused normal lack apparatus simulating pressure. In this research study, a simulator was designed and manufactured for study buried soils over dip–slip fault, by which overburden pressure can be applied model soil. The...
