| 摘 要： | 首先就工程爆破施工中建筑物的振动监测问题进行了较为全面的介绍,从振动速度、频率、地基土壤性质等方面分析了爆破地震波引起结构物破坏的原因,并结合工程实例,就结构物的振动数据采集提出了见解.研究认为,建筑物的安全阈值应根据结构最易发生破坏的部位所采集的数据为标准来进行判断,而不是根据结构物地面所采集的数据来确定.

| Abstract: | The structure's response vibration and its damage caused by the blasting seismic wave is analyzed in this paper. We propose the causes, which contribute to the structure's damage in engineering blasting, should include the frequency, the maximal amplitude of the blasting seismic wave's velocity, the soil's characteristics, etc. By analyzing the data of structure's response vibration, we believe that the criterion by wihich we estimate structure's damage caused by the blasting vibration, must be based on the data collected from the most sensitive and unsubstantial part of the structure, instead of the structure's ground. |
