YANG-Qi, LENG Wu-ming, DENG Zong-wei, et al. Universal calculation formula of additional vertical stress under bridge abutment due to embankment and conical slope[J]. 2008, 29(3).DOI:
The embankment on the back of bridge abutment and the conical slope produce additional vertical stress in the bridge abutment subsoil; the stress is the key parameter to calculate the differential settlement
lateral movement of the bridge abutment
the lateral pressure and flexibility of the abutment’s pile foundation. Based on the elastic theory formula and the superposition principle
the calculation formulas of the stress are deduced so as to solve the problem of the existing code only applicable to single-track roadbed and error due to looking up table together with interpolation. In addition
