无锚点吊推用门架设备的应力测试

通过对无锚点吊推法采用的大型门架设备进行静态应力测试以及实际吊装过程中的现场跟踪测试，结合对门架设备的结构分析，改善了吊推方案，保证了高116m、164t的大型火炬塔架的顺利吊装成功，为同类吊装工程提供了参考数据。

Stress test for non-anchoring point gantry hoisting equipment

The hoisting program is modified after static stress test of large gantry equipment used in non -anchoring point hoisting, in-situ tracking test in the process of pratical hoisting, and structural analysis of gantry equipment. It ensures sucessful hoisting of large torch towers with 116m height and 164t weight, and provides reference data for the same kind of hoisting engineering.
