| Abstract: | This paper takes cast-in-place constructional skill of continuing girder in Beijing-Hangzhou grand canal bridge which cross 338 road with （ 60 ＋ 100 ＋ 60） m as example, establishes simulation model by using ANSYS soft- ware, it also makes optimal design for sus-taining frame, establishes pre-camber curves of construction and pro- vides basis for decision-making for construction control. |
