摘要

摘要: 为探索爆破振动作用下人体动态响应的量化评价方法，在严格安全控制条件下开展单受试者原位爆破试验，结合数字图像相关技术与心电变化同步测量系统，分析不同强度爆破振动作用下人体结构体表动态响应特征，并建立了本试验条件下考虑身高影响的人体分区（腰部以下、腰部以上）峰值振动速度拟合关系；鉴于原位爆破试验的安全性制约，进一步借助室内振动台试验，基于心率变异性评价指标的对比分析，论证振动台模拟爆破振动开展人体感知试验的可行性。研究结果表明：人体垂直振动速度显著高于水平振动速度，垂直方向为主振方向；垂直方向振动速度则呈现“腰部以下衰减、腰部以上放大”的特征，与地表振动速度相比，腰部以下区域衰减率为55.7%～65.9%，腰部以上区域振动速度放大1.25～1.74倍；水平向振动速度自脚部至头部呈衰减趋势，衰减率达52.6%～60%；原位试验与振动台试验所获心率变异性指标误差小于10%，证实了采用振动台模拟爆破振动研究人体感知的可行性。

Abstract: In complex and sensitive environments, minimizing the disturbance of blasting vibration to surrounding residents is the primary concern during blasting construction. To explore a quantitative evaluation method for human dynamic response to blasting vibration, this study conducted single-subject in-situ blasting tests under strictly controlled safety conditions. By integrating digital image correlation (DIC) with a synchronous electrocardiogram (ECG) measurement system, the dynamic response characteristics of the human body surface under varying blasting vibration intensities were preliminarily analyzed. A height-dependent fitting relationship for peak particle velocity (PPV) was established under the present test conditions, with the body divided into two regions: below the waist and above the waist. Given the safety constraints of in-situ blasting tests, laboratory shake-table tests were also conducted. A comparative analysis using heart rate variability (HRV) evaluation indices was performed to preliminarily demonstrate the feasibility of using a shake table to simulate blasting vibration for human perception studies. The preliminary results indicate that under the present test conditions, the vertical vibration velocity of the human body is significantly higher than the horizontal velocity, with the vertical direction identified as the dominant vibration direction. The vertical vibration velocity exhibits a characteristic pattern of “attenuation below the waist and amplification above the waist”. Compared with the ground surface velocity, the attenuation rate in the lower body region ranges from 55.7% to 65.9%. The vibration velocity in the upper body region is amplified by a factor of 1.25 to 1.74. The horizontal vibration velocity decreases from the feet to the head, with an attenuation rate of 52.6% to 60%. The error in HRV indices obtained from the in-situ and shake-table tests is less than 10%, preliminarily confirming the feasibility of employing a shake table to simulate blasting vibration for human perception research. These exploratory in-situ tests provide a methodological reference for quantifying human vibration response and studying perceived ECG changes due to blasting vibrations.
