Seismic Behaviour of Pavements-An Approach Towards Seismic Resistance Design of Pavements
From past to date, earthquake road damages have been observed in India and worldwide. Road networks play a key role in natural and man-made disasters. Several researchers have been reported road, bridge, and tunnel damage due to earthquakes. However, very less literature and almost no guidelines have been established against seismic resistance design of pavements. In the present study, two-dimensional finite element analysis has been performed for seismic response of road under surcharge load as traffic loads. The three-layer road is modelled as three nodded triangular elements with an average element size of 1/10th of the seismic event wavelength. The seismic excitation is applied at the base of the model, and the model has been verified using the wave propagation theory. The lateral and vertical response of the road has been reported in terms of response spectra and displacement with depth. The result shows that road embanks are more vulnerable to seismic excitations, and significant aggravation of ground motion is observed at the top of pavements compared to free field conditions. A parametric study also has been reported in the present study.
