摘要
结合常州市马公桥工程的建设,对采用支座位移法来施加预应力、避免桥面混凝土开裂的技术进行研究。通过对施工中的实测数据和仿真计算结果的比较,明确了该施加预应力方法的实际效果,并得出有关经验和建议。
In construction of the Changzhou Magong Bridge project, engineers adopted the support offset method to apply prestress in order to avoid deck concrete cracks. In this article, the author studies this technology, compares practically measured data and simulation calculation results, states effects of this prestress construction method and provides relevant experiences and advice.
