Weakened Support Detection Based on Road Slab Vibration Response

Abstract:

This paper presents a vibration testing method to monitor the deterioration and weakened support on slabs of cement concrete pavement. After discussing on methods for void evaluation, a dynamic finite element model of road slab with Winkler foundation assume is established according to the structure of slabs both in good condition and conditions with varying degrees’ defects, and computer simulation to vibration characteristic is conducted and a corresponding measuring system is proposed. Its results can be used to guide actual test.
