摘要:
结合福建漳州核电厂一期工程场地平整土石方工程施工实例，为取得厂区岩体爆破施工时的振动能量分布，优化核电站二期工程爆破技术方案设计，对爆破振动数据进行采集，应用小波变换方法对具有短时非平稳特点的爆破振动信号进行了特征分析。基于小波变换的时-频特性和分层分解分析对比可知，爆破振动持续时间在不同方向上存在差异，且振动持续时间表现出与频率的反相关关系；振动信号的频率分布在不同振动方向上也呈现差异性；由于地形及岩性的因素作用，核电厂区爆破振动的能量分布主要集中在10~50 Hz范围内。
Abstract:
Construction of site leveling earthwork for the first-stage construction of the Zhangzhou Nuclear Power Plant in Fujian Province was studied. In order to optimize the design of the blasting technical scheme for the second-stage engineering of the nuclear power plant, vibration energy distribution during the blasting construction of the rock mass in the plant area was obtained by collecting blasting vibration data. Characteristics of blasting vibration signals with short-term non-stationary characteristics were analyzed. Based on the analysis and comparison of time-frequency characteristics and layered decomposition of wavelet transform, it was found that the duration of blasting vibration is varied in different directions, and the duration of blasting vibration is inversely related to the frequency. The frequency distribution of vibration signal also differs in different vibration directions. Due to the effect of topography and lithology, the energy distribution of blasting vibration is mainly concentrated in the range of 10-50Hz.
