摘    要:随着我国改革开放、经济发展的不断深入,原有高速公路运能已远远不能满足日益增长的运量需求.本着“节约土地、节省资金、发挥最大效能”的理念,国有多条既有高速公路实施了改扩建工程.在这些工程中,既有天桥拆除作业成为施工难点.结合工程实例,对天桥炸点设置的选择与验算进行介绍,以期为今后类似工程提供借鉴.

关 键 词:高速公路  天桥  爆破拆除

Abstract:With the development of China' s reform and opening up, the economy continued to deepen, the existing high- way capacity can not meet the increasing traffic demand. Based on the spirit of "save the land, save money, play a maxi- mum efficiency" concept, the existing highways reconstruction projects were implemented. In these projects, the bridge' s demolition became difficulties. Combined with practical engineering, the selection and checking of explosion point set about the overcrossing bridge are introduced, which can provide reference for similar works in the future.
Keywords:highway  overrcossing bridge  demolition blasting
