摘要
由于建设工程的快速发展,机施振动、爆破施工逐渐成为房屋墙体开裂的重要原因之一,并与温度裂缝等结合,成为房屋裂缝的主要原因。本文针对具体的工程实例,通过现场振动速度的测试,评价机械振动对房屋的影响;通过分析房屋裂缝的产生位置和形态,进行理论计算,了解裂缝产生的主要原因。
Machine vibration and blasting in the rapid development of construction projects,together with temperature,are becoming important causes for housing cracking.This paper is aimed at evaluating the impact of mechanical vibration on housing cracking by analyzing the examples of some specific projects,in which the on-the-spot vibration velocity and cracks in housing location and shape are measured for the purpose of carrying out theoretical calculations to understand the main reason for the cracks.
