摘要/Abstract

摘要： 为研究复杂结构高层建筑爆破坍塌过程及效果,对含有多核心筒且存在中空结构建筑进行爆破模拟。模拟建筑为中空-四核心筒-框架结构,核心筒贯穿建筑整体。采用颗粒流方法对该建筑进行建模,并使用基于颗粒流的爆破算法实现爆破模拟。根据建筑结构特点及核心筒与建筑中心距离,采用三组爆破方案实施爆破,对爆破过程及爆破结果进行了分析。结果显示爆破点距建筑中心越近爆破效果越好;爆破点的设置应使爆破过程尽量增加建筑坐塌时间,提高坐塌速度,减小建筑倾倒高度。根据建筑坍塌结果给出了可使该建筑完全发生坐塌的爆破方案。

Abstract: In order to study the complex high-rise building structure collapse process and effect of blasting, the blasting simulation of building containing multi-core tube and hollow structure are performed. Simulation building has hollow-four core tube-frame structure and the core tube throughout the whole building. Particle flow method is used to model the building, and blasting simulation is implemented using the blast algorithm based on particle flow. According to the structure characteristics and the distance of core tube and architecture center, the implementation of blasting is three groups design. The processes of blasting and the blasting results are analyzed. Results show that the distance of the blasting point from the center is closer, the better blasting effect. Design of blasting point should try to increase the building sitting collapse time, increase the speed of sitting collapse, and reduce height the dumping during the blasting process. According to the result of building collapse, the building fully sitting collapse blasting scheme are given.

Key words: construction blasting, multi-core tube, hollow, blasting scheme, effect analysis
