Abstract Research purposes: The transition section is a joint section between rigid abutment or other structures and flexible embankment and it is a mutant of plastic deformation and rigidity in structure．So during the construction，the measures must be taken for reducing the plastic deformation difference between them，to control post—construction settlement and to achieve smooth transition．Combination of the relevant transition section of Pre—station Bidding IV of Shanghai—Nanjing intercity railway，this paper analyzes the observed data on the settlements during construction and after construction，and summarizes the settlement law．
Research conclusions: Using graded gravel to reinforce the transition section，the total amount of settlement is not large with a regular pattern．The largest amount of settlement of the transition section OCCUrs at the area where is 10—20 m away from structures，and the amount of settlement is proportional to filling height，and the settlement velocity is in the positive correlation with filling time．With the”heaped loading and pre—pressing”after construction．the overall settlement tends to steady state．
