在爆破振动范围内,介质质点围绕其平衡位置做自由振动。爆破振动条件下的质点振动轨迹是爆破振动研究的基本课题之一。它说明了介质初动的时间、初动方向、运动路径和轨迹等问题。这对于研究建筑物、构筑物破坏的原因、确定破坏判据、探讨爆破振动传播规律都有重要意义。目前,有关爆破振动基础理论的研究和整个地震学的研究一样,仍处于初始阶段,有些理论和假设仍不能解释工程上出现的问题。本文试图根据近年来的实测结果对这方面的问题进行一些初步分析。
In the blasting vibration range, the medium particle makes free vibration around its equilibrium position. The particle vibration trajectory under the condition of blasting vibration is one of the basic topics of blasting vibration research. It shows the start of the media time, the initial direction, the path and trajectory and other issues. This is of great significance to the study of the reasons for the destruction of buildings and structures, the determination of damage criteria and the discussion of the propagation laws of blasting vibration. At present, the research on the basic theory of blasting vibration is still in the initial stage as the researches on the whole seismology. Some theories and assumptions still can not explain the engineering problems. This article attempts to make some preliminary analysis of the problems in this area based on the measured results in recent years.
