摘要(Abstract)：

分段爆破解体原地倾斜塌落法是针对高宽比接近于1或小于1的建筑物爆破拆除的一种有效方法。该技术是在巫山县移民拆迁工程中,根据当地建筑物的周边环境、地形地势和建筑物结构特点研究制定并进行应用的。这一技术的关键点是对同一时段爆破区域内横梁的爆破处理和段间爆破时差250ms的控制。经实践证明,应用该技术的工程有着施工量小、装药量少、塌落震动小、解体充分、塌落场地范围小等优点。
Buildings to be demolished by blasting collapsing at original ground in inclining is an effective method in demolishing constructions with the ratio of its height over length close to 1 or less than 1.This method was applied successfully in Wushan county immigration project according to the building peripheral environment,the terrain topography and the unique feature hold by the building itself.The key point of this technique was the control of the time interval.The interval time between the treatment of the blasted crossbeam and the next objects has to be delayed 250ms at least.The practice proved the demolition method has below features: less operating works,less explosive charge,low vibration in collapsing,good disintegration and small collapsing region.
