摘要
以宁波大碶疏港公路延伸段工程主线桥第七联为例,利用桥梁博士平面杆系理论和Midas Civil梁格法分别建模计算,分析了本桥通车运营2a,在距梁端部约2.5~5m范围内出现的横、竖向裂纹的成因,并提出了处理措施。
This paper takes the seventh link of the main line bridge of Ningbo Daqi Shugang Highway Extension Project as an example.By using plane pole system theory of Dr. Bridge software and beam grid method of Midas Civil, this paper analyzes the causes of transverse and vertical cracks within the range of about 2.5~5 m from the beam end after two years operation, and puts forward the treatment measures.
