DENG Ya-hong, PENG Jian-bing, FAN Wen, et al. Dynamic deformation response of pavement structure subjected to hidden holes in loess[J]. 2008, 29(3).DOI:
an elastoplastic numerical analysis is made to analyze the effect of hidden holes in loess on the dynamic deformation response of pavement structure. In order to reduce the effect of wave reflecting on artificial boundary
transmitting boundary and semi-infinite element are respectively used to treat the lateral and underside boundaries. The cycle of dynamic load and the diameter and depth of hidden holes in loess are the mainly considered three factors. Finally
based on the numerical calculation results
their effect laws on deformation response of pavement structure are analyzed.
