Abstract

Abstract: It is a normal method to cast in place on construction frame．but the box-beam would collapse during casting be· cause of the failure of construction frame.It is necessary to control the stress situation of fame．The analyses of test results are made.

Key words: construction frame, stress test, control

摘要： 搭设支架现浇砼箱梁是工程上常用的施工方法之一，由于支架垮塌导致的工程事故时有发生，因此，对支架在砼浇注过程中的受力情况进行监控是很有必要的．对实际工程融桥大道螺旋桥施工现浇支架在施工过程中的应力及箱梁的挠度进行实时监测，并对测试结果进行了分析．

关键词: 支架, 应力测试, 监控
