ANALYSIS AND STUDY ON MAIN CONTROLLING FACTORS OF SETTLEMENT OF BACKFILL SOIL BEHIND BRIDGE AND CULVERT PLATFORM IN HIGHWAY ENGINEERING
The back of highway bridge and culvert platform belongs to rigid and flexible transition area,which plays an important role in driving quality.Combined with the specific project,the mechanism of bridge head jump is mainly caused by the existence of"wrong platform"or"additional slope",the main control factors of backfill soil settlement are summarized,and the sensitive factors of bridge head deformation are obtained from the aspects of design,construction and materials.
