Abstract
Nanjing to Anqing railway construction project traverses over No. 321 provincial road, and the angle between the new line and the existing road is only 16. 45 ° . In order to solve the structure height restriction and small skew angle, ( 39. 6+18. 7+41. 3+18. 7+39. 6 ) m rigid frame of special shape is selected after bridge type comparison. The paper focuses on the arrangement and design of the special shaped rigid frame with skylight and side window. The behavior and characteristics of the special shaped rigid frame are summarized, and the differences between two calculation methods of spatial and plane are compared and analyzed. The calculation results show that the structure can meet the requirements of the strength and stiffness of ballastless track bridge.关键词
