| Abstract: | Vehicle bumpiness at the transition section of the roadbed and the bridge is a difficult problems in the highway construction, which has an adverse effect on the rapid and stable running of the vehicles. This paper, based on bridge construction on Hengzao highway, gives the scheme of curing the soil depression with geotechnic grid. By means of test on the site, the merits and effectiveness of the geologic grid is analyzed, and experience is accumulated for dealing with the vehicle bumpiness at the bridge and roadbed joint. |
