摘要
重庆市嘉华大桥是重庆市政基础设施建设项目之一,是跨越嘉陵江的预应力混凝土刚构大桥。为了确保施工中的结构安全和施工质量,在施工全过程中对大桥进行了施工监测。根据桥梁的实际特点和桥梁刚构的力学特征,主要研究桥梁上部结构控制截面的应变及温度分布情况,分析上部结构竣工后结构实际状况,实时控制施工方案及进度,确保桥梁结构安全。
Chongqing Jiahua bridge is one of the projects of Chongqing infrastructure construction. It is a pre-stressed concrete rigid frame bridge through Jialing River. In order to insure structural safety and constructional quantity, we carried on the whole process monitoring to the big bridge. According to the actual characteristics of bridges and the mechanical characteristics of rigid frame, main point is the controlling of contingency and temperatures at the upper part structure.
