ABSTRACT

The method of accelerometric control of transport streams, which is part of the system of geotechnical monitoring, is considered. The main features of accelerometer sensors application in solving the identification problem of parameters of the transport stream are described. A mathematical model of the vibration load on local sections of the road is described. It is proposed to evaluate the effect of the transport load on the basis of the recorded parameters of the propagation of vibration effects arising from the movement of vehicles. In addition, it is proposed to evaluate the dynamics of load in the elements of foundations of the building arising from the effects of transport stream vibrations. Based on the spectral analysis of accelerometer signals, it is proposed to identify the parameters of vehicles (mass, speed) and determine the dominant frequencies of vibration effects on the elements of the foundation of structures located near roads. Carrying out the analysis of the calculated natural oscillations of structural elements of structures with the data of accelerometric control of the transport stream, it is possible to estimate and predict the influence of the transport stream on the stability of the soil structures.

Keywords: geotechnical monitoring, geological environment, transport streams, accelerometric control, acoustic-vibrational waves
