本文研完的主要目的在于探讨连续弯箱梁桥在特定的荷载情况下的各种受力特征和变形情况。试验桥模型是根据加拿大渥太华市的 CyrvilleRoad 桥作为原型的。由试验实测所得的应力、应变值与理论计算值校核,得到了满意的结果;修正后的理论挠度与实测挠度,其误差在6%以内;当宽跨比L/B=8.89时,其挠度的横向分布规律基本上呈线性比例关系。本文系采用“有限条法”的计算机程序进行理论分析。 The main purpose of this paper is to study various stress characteristics and deformation of continuous curved box girder bridge under certain load. The test bridge model is based on the Cyrville Road Bridge in Ottawa, Canada. The experimental results obtained by the stress and strain values ​​and theoretical calculations verify that satisfactory results have been obtained; the theoretical deflection and measured deflection after correction, the error is within 6%; when the span ratio L / B = 8.89, its The horizontal distribution of deflection is basically a linear proportional relationship. In this paper, the “finite strip method” computer program for theoretical analysis.
