在城市改建中,高层建筑打桩对周围建筑的影响是一个很普遍的问题,过去往往从基础工程方面加以处理而对结构物的位移、应力等缺乏定量的了解。本文运用不均匀加速度场的概念,分析了打桩振动与地震动的区别,对结构物进行了打桩时程反应分析,取得了结构反应量的定量结果,并经实测结果证明本文的计算方法是可行的,为今后解决同类问题开辟了一条新的途径。
In urban redevelopment, the impact of high-rise building piling on the surrounding buildings is a very common problem. In the past, basic engineering was often used to deal with the lack of a quantitative understanding of the structure’s displacement and stress. In this paper, the concept of the non-uniform acceleration field is used to analyze the difference between the pile vibration and the ground motion, and the structural time history is analyzed. The quantitative results of the structural response are obtained. The actual measurement results show that the calculation method is feasible. , to open up a new path for solving similar problems in the future.
