Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blasting protection, in particular to a test method for quantitatively evaluating human response and perception of blasting vibration. BACKGROUND

[0002] The vibration generated during the blasting process in the fields of construction engineering, mining, transportation construction, etc. not only affects the surrounding buildings and facilities, but also significantly disturbs the human comfort of residents and workers. Long-term exposure to the blasting vibration environment may cause discomfort and even health problems in the human body, such as fatigue, anxiety, headache, insomnia, and cardiovascular diseases. Therefore, it is of great significance to establish a scientific and accurate blasting vibration human comfort evaluation system to protect personnel health, optimize blasting operation design, and reduce social conflicts. The blasting vibration human comfort evaluation system analyzes the intensity, frequency, duration, and other multi-dimensional parameters of blasting vibration to evaluate the impact of vibration on the human body, providing a theoretical basis and technical support for the safety control and environmental impact assessment of blasting operations. In addition, with the increasing attention to environmental protection and health issues, the impact of blasting vibration on human comfort has become an important factor in engineering design and safety management.

[0003] Currently, there are several blasting vibration human comfort evaluation systems internationally and domestically, mainly including the following: 1. National standard "Blasting Safety Regulations" (GB6722), which arranges vibration sensors around the buildings, structures, or ground in the blasting area. By combining the peak vibration velocity collected by the sensors and the long-term experimental research and engineering practice, the physiological response of the human body to vibration is summarized, providing a scientific basis for the safety of the human body around the blasting operation. The peak vibration velocity of the measuring point is the core index for evaluating the safety of blasting vibration in this evaluation system. 2. Fanger comfort model extension, the original Fanger model is based on the human body heat balance equation to predict the thermal comfort (PMV, Predicted Mean Vote) and dissatisfaction (PPD, Predicted Percentage Dissatisfied) of the human body. The extended model introduces vibration perception based on this, taking vibration acceleration as a new variable to affect the overall comfort evaluation. The system lets the subjects conduct thermal comfort and vibration perception experiments in different environmental conditions (temperature, humidity, wind speed) in the laboratory or on site. It combines thermal comfort (PMV) and vibration perception (vibration acceleration) to establish a comprehensive comfort model to analyze the impact of different environmental conditions and vibration intensity on comprehensive comfort, and determine the comfort threshold of vibration acceleration, providing a basis for comfort control in blasting operations or other complex environments. The core of this system is to predict the thermal comfort of the human body by considering factors such as environmental temperature, humidity, wind speed, clothing thermal resistance, and human activity.

[0004] However, the above blasting vibration human comfort evaluation system has certain disadvantages: the national standard "Blasting Safety Regulations" (GB6722) evaluation system only takes vibration velocity as the evaluation index, without considering other important parameters such as vibration frequency, and cannot comprehensively reflect human comfort.

The test method for quantitatively evaluating human response and perception of blasting vibration according to claim 2, characterized in that, The S2 includes the following steps: S21, set a set of vibration table with vibration frequency, vibration direction, vibration mode, vibration intensity adjustment function; the loading frequency adjustment range of the vibration table is 0.1 Hz~100 Hz; the vibration table is used for outputting horizontal, vertical and longitudinal vibration; the vibration table supports fixed frequency and sweep frequency vibration mode; S22, layout of blasting vibration monitor in the center of the vibration table; S23, let the volunteer wear the same white body suit as in S12 stand on the blasting vibration monitor; S24, arrange the light source on the left and right sides of the volunteer's front to ensure that the black dots on the white body suit on the volunteer are clearly visible; S25, layout of white curtain behind the volunteer; S26, erect high speed camera in front of the volunteer's front 5 m, adjust the direction of high speed camera camera, so that the volunteer can be completely photographed by high speed camera; S27, carry out the first human vibration response vibration table test, after the volunteer is ready, the test personnel adjust the vibration parameters of the vibration table and start, the vibration table starts to vibrate, realize the vibration table test of vibration human response under different vibration working conditions by changing the vibration parameters of the vibration table many times; S28, after the test, collect the vibration data of the vibration table collected by the blasting vibration monitor under the volunteer's feet; use computer software to calculate and analyze the vibration and displacement data of the black dots of the white body suit obtained by the high speed camera through shooting the volunteer.

4. The test method for quantitatively evaluating human response and perception of blasting vibration according to claim 3, characterized in that, The S3 includes the following steps: S31, comparative analysis of the data obtained in S17 and S28; S32, repeat S27-S28 until the error between the data in S28 and the data in S17 is less than or equal to 10%, which proves that the indoor vibration table test can simulate the field blasting test, and records the data in S28 and the data in S17 with an error less than or equal to 10%, and obtains the vibration table parameters for simulating field blasting vibration, including vibration frequency, vibration direction, vibration mode, and vibration intensity of the vibration table; S33, remove the light source and high-speed camera on the vibration table; S34, the volunteer stands on the vibration table in a standing posture, and the tester adjusts the vibration parameters of the vibration table to the values in S28 that can simulate field blasting vibration; the volunteer holds a wireless electrocardiogram recorder and stands on the indoor vibration table; S35, carry out the second vibration table test, and first record the heart rate variability frequency domain index value of each subject in a resting state after the test starts; then adjust the vibration table parameters so that the volunteer starts to vibrate without knowing the vibration parameters; S36, record the human perception of the volunteer; S37, recruit 40-200 volunteers again, and use different vibration table parameters to carry out vibration table tests on different volunteers, statistically analyze the human vibration response data under different vibration working conditions, and calculate the heart rate variability frequency domain index value under different vibration working conditions; the human perception is divided into five levels: almost imperceptible, perceptible, obvious, uncomfortable, and repulsive; S38, statistically analyze the heart rate variability frequency domain index value of the volunteers in different vibration working conditions in step S37, and calculate the average growth rate of the heart rate variability frequency domain index value of the volunteers in different vibration working conditions compared with the resting state.
