利用300T吊车架设复杂地形条件T梁支腿稳定性检算

T-beam Leg Stability Inspection under Complex Terrain Conditions by Using 300T Crane

在铁路桥梁施工中,由于拆迁、铺架条件、连续梁施工等各种因素限制,架梁经常要采用汽车吊进行,汽车吊架梁可以根据墩身完成情况随时组织。本文根据施工中发生的实际工程案例,介绍复杂地形条件下需要进行的各种安全检算,以及通过检算得出的一些经验方法,为以后吊装施工提供相应的借鉴。

In the construction of railway bridges, due to various factors such as the demolition, the condition of the racks and the construction of continuous beams, the car crane is often used for overhead cranes. The car hanger beams can be organized at any time according to the completion status of the pier body. Based on the actual engineering cases that occurred during the construction, this article introduces various safety inspections that need to be carried out under complex terrain conditions, and obtains some empirical methods through the calculations, to provide corresponding reference for future hoisting construction.
