摘要
针对以往扩建公路新旧桥拼接部位混凝土容易开裂的问题,结合桥梁拼接混凝土应遵循的基本规律,从原材料、配合比、施工质量控制、开放交通前混凝土强度要求等方面论述了如何有效地扬长避短,解决桥梁拼接混凝土开裂问题。
Aiming at problems of cracks in the new and old bridge joint part in the expansion road project,the paper combining the basic law in the bridge joint concrete,illustrates the way of how to show its advantages and hide disadvantages from the raw materials,proportional ratio,construction quality control,and the requirements on concrete strength before open the traffic,so as to solve the cracks on the concrete joints.
