摘要(Abstract)：
近年来，上海地区深基坑支撑围护体系通常采用爆破法拆除。然而，有支撑的工地往往位于繁华地段，周围建筑物较多且距基坑较近，在支撑爆破过程中必须控制爆破震动，保护周围建筑物。本文通过分析实例，提出了在支撑爆破时控制震动的方法。
In recent years,it is usually to demolish the reinforced concrete brace system with blasting in Shanghai.However,since the buildings under construction aregenerally located at the downtown districts or the residential areas of the cities,so it is necessary to control the ground vibration during the blasting of reinforced concrete brace system and to protect the building surround the blasting area.In this paper analyzing a real model and put forward some ways to control the blasting vibration of reinforced concrete brace system.
