摘要

以三峡堤防工程基础开挖为研究对象，对堤防工程基础开挖爆破地震波的振动监测方法和监测物理量的选择进行了研究。通过对爆破振动监测结果的回归分析，确立了爆破振动速度的传播衰减规律。结合工程实际，对基础开挖爆破产生的地震波的振动频率与爆区周围建（构）筑物的自振频率进行了对比分析；经对比分析，此次开挖工程爆破引起的振动频率远大于周围民房结构的自振频率，从而保证了周围建（构）筑物的安全。同时，结合该堤防工程开挖爆破施工，从建（构）筑物的安全振动速度和爆破振动的安全距离两个方面确定了爆破振动安全控制建议标准。研究分析表明，本次爆破工程的振动速度和安全距离都在爆破振动安全控制标准的范围内，从而说明了本次爆破工程圆满安全地完成了施工任务，保证了爆破时周边建（构）筑物的安全；其研究对指导基础开挖爆破施工和保证地面建筑物安全起到了重要作用。

Abstract

Based on bedrock digging of embankment project in the Three Gorges Proiject

the choice of measurement method and object of vibration by blasting earthquake wave induced by bedrock digging of embankment project were studied. Via regression analysis of the results of measurement on blasting vibration

the spread and attenuation regularity of vibration velocity of blasting were established. Combined the project

the vibration frequency of earthquake wave induced by blasting of bedrock digging and the vibration frequencies of surrounding buildings in blasting zone were contrasted and analyzed. After analyzing

the vibration frequency by blasting of this digging project was far bigger than the itself vibration frequency of structure of surrounding civilian house; consequently the safety of surrounding buildings were assured. At the same time

integrated the digging blasting construction of embankment project

the safety control standard of blasting vibration by this blasting engineering was confirmed from the two aspects such as safety vibration velocity of buildings and safety distance of blasting vibration; consequently

it is shown that the construction task of this blasting project were done safely; and the safety of surrounding buildings were assured while blasting was on. This research has played an important role in coaching blasting construction of bedrock digging and assuring the safety of ground buildings.
