摘要(Abstract):

拱式结构的主要特点是在竖向荷载作用下产生水平反力。本文对工程中常用的无铰拱式结构进行了力学分析,提出了相应的拆除爆破方法,并通过工程实例进行了验证。
The main characteristic of arched construction is to produce horizontal thrust under vertical loading.In this paper,the hingeless arched construction in common use is analyzed with mechanics,the appropriate method of demolition is put forward.The demolition method is proved by an engineering example.
