摘　　要：控制爆破技术在国内外应用较广泛,目前,国内关于既有建筑物近距离控制爆破应用的研究较少,尤其是与既有建筑物距离仅1.0 m的控制爆破技术更少见。文章以温州液化天然气(LNG)接收站项目配套码头工程为依托背景,通过探索既有建筑物超近距离爆破安全防护关键技术,从地质情况、爆区环境、保护对象与爆区相对位置、地震波、衰减规律及采取的保护措施等方面,全面剖析了与既有建筑物超近距离爆破的安全防护,并采取相应的关键技术措施,旨在保护既有建筑建筑物。Controlled explosion technology is widely used at home and abroad.At present,there are few studies on the application of controlled explosion close to existing buildings,especially the controlled explosion technology with a distance of only 1.0 m from existing buildings.Based on the supporting wharf project of Wenzhou Liquefied Natural Gas(LNG)Terminal project,the key safety protection technology for explosion ultra-close to existing buildings is explored.From the aspects of geological conditions,explosion area environment,relative position of protection object and explosion area,seismic wave,attenuation law and protection measures,the safety protection of explosion ultra-close to existing buildings is comprehensively analyzed,and corresponding key technical measures are taken to protect existing buildings.
