| Summary: | Based on the fundamental conception of hysteretic systems random vibration, this paper presents a simplified model to
analyze the hysteretic nonlinear dynamic response of concrete covering consolidation grouting. The proposed model aims
at capturing the hysteretic characteristics of the concrete covering nonlinear behavior and revealing the importance of
grouting pressure dynamic load affecting the concrete covering uplift behavior. To this end, the proposed approach
considers the concrete covering as Bernoulli-Euler beam, and then incorporating the Bouc-Wen model, simulates the soil
force on the concrete covering, the one that beneath the concrete covering can be considered as hysteresis spring and
dashpot in parallel. According to the actual grouting parameters, amplitude-frequency response characteristics of concrete
covering are discussed under different external load. A comparison of model calculation results and real-field
experiments are used to evaluate the effectiveness of the presented method, the results show that the predictions of the
model correspond with the measured values. |
