Method of Determining the Length of Approach Slab for Highway Bridge

Abstract:

Approach slab is mainly used to slowdown or reduce uneven settlement of bridge heads as far as possible. Setting approach slab at back of bridges and culverts is an effective and necessary way to avoid faulting slab ends between abutment and road in high-grade highway. It has come into general application and achieved good results. But nowadays, approach slab is designed based on previous experience or being set a size parameter directly instead of being made a special design. Theory and experience that the design based on is unreasonable. Author confirm the need for setting approach slab and give the reference value about length of approach slab for different grade highway according to analysis and study on the forced state of the moving vehicles at highway-bridge junction with or without approach slab.
