Abstract：Research purposes: The study is done on the influences of land subsidences on the bridges of high-speed railway at different stages in different areas and the preventive and engineering rmeasures for subsidence are presented for the purpose of providing reference to survey, design and construction of high-speed railway.
Research conclusions: In the central area of land subsidence and vicinity of the pumping well, the uneven subsidence is more serious , which much influences the bridge structure. In the extended area of land subsidence , the deformations of strata and bridge caused by land subsidence are ,longitudinal ones with large subsidence volume, but which has little influence on the bridge structure. In the area of land subsidence, the subsidence happens slowly, which has a little influence on the construction of bridge, but the large subsidence may happen in some places, so it is necessary to select bridge site rationally, optimize the layout and structure type of bridge, adopt simply-supported structure and take the engineering measures to enhance the bridge capacity against the subsidence.
