Ground settlement in the mainland of China is becoming serious, traffic safety in some areas of settling funnel has been endangering. Since 1997, the Research Institute of Highway has been monitoring some structures of a highway for some years, it was found that some vertical deformation occured as fast as ground settlement, with the maximal settling velocity reached - 20mm per year.
