工业企业总平面设计防振间距的研究

THE STUDY ON VIBRATION PROOF DISTANCE OF TOTAL PLANE DESIGN FOR INDUSTRIAL ENTERPRISES

本文阐述了工业企业中各种振源地面振动测试技术、测试方法、实测的情况和结果。实测结果表明:不同的振源具有不同的振动波形、不同的主频率、不同速度峰值和衰减规律及弹性波随深度的衰减具有指数函数性质。给出了以振动速度、位移为控制值的工业企业总平面设计的防振间距表和土壤的波能量吸收系数及不同土壤的防振间距换算系数表。

In this paper, the test and measurement technique, analysis method, practical measurement casesand test results of ground vibration with various sources at industrial enterprises are described. Themeasurement results show that there are different vibration waveforms, different main frequency, differentvelocity peak values and decay law with different vibration, and indicate that the decay of elasticitywaves along the depth possesses the characteristic of exponential function. The tables of vibra-tion-proof distance based upon velocity or displacement controlled values, and the table of soil's waveenergy absorb coefficient and conversion coefficient of vibration-proof distance of different soil are pre-sented.
