摘要
以云南省澜沧江干流上托巴大桥连续梁上承式箱型拱桥施工监测为背景,根据桥梁结构、所处环境等因素布置测控方案,并根据此方案对该桥各施工阶段线形进行了基于MIDAS的有限元仿真预测设置预拱度值。结合施工阶段现场监测结果,验证了此监测方案的合理性,对实际工程有切实的指导意义。
In this paper , based on the construction monitoring of continuous box girder arch bridge of Shangtuoba Bridge on Lantang River in Yunnan Province, the monitoring and control scheme is arranged according to the bridge structure and environment. Based on this scheme, the MIDAS finite element simulation predicts the pre-camber value. Combined with the results of field monitoring at the con- struction stage, the rationality of this monitoring scheme is verified, which has practical significance for practical engineering.
