摘要
针对沈平高速公路新旧盖梁连接后浇带预留与否这一问题,分别从浇筑过程中混凝土连接处截面应变应力、施工过程中悬臂端振动、墩柱沉降等进行跟踪监测,并采用成桥荷载试验的方法对其进行效果评价,结果表明,在措施得当条件下拼宽桥盖梁整体浇筑不影响盖梁使用功能,并且可以提高施工效率。
According to the post - pouring settlement belts of the new - old cap beam of Shenyang - Siping expressway reserved or not, track and monitor the data for the strain - stress of the concrete joint section in pouring process, the vibration of cantilever end during construction and pier column settlement respectively. It is used to evaluate the performance by the method of bridge load test. The result is shown that the method of the post - pouring settlement belts cancelled not only has no influence to use function but also can improve the efficiency for he cap beam in the condition of appropriate measures.
