Abstract
The technical seismicity effect assessment caused by traffic is the aim of article. The highway structure, as the mine of vibration, includes common layers and also special materials with dumping properties. It is the geomesh reducing the crack creation caused by fatigue, the tension strength increase and excess settlement The stress concentration in the bitumen structure reduces and separates into reinforcement. the machines sensible to vibration will be located in the production factory and it means the vibration level estimation caused by future mine of vibration is needed. The dynamic bedrock diagnostics was needed to provide for prognosis numerical model of dynamic effect ground half-space and dynamic effect future highway in the location of Presov-Haniska and the dynamic interaction of this mechanism (the ground – pavement base structure). The dynamic diagnostics of bedrock main aim was determination of base dynamic parameters due to wave method coming out from surface wave stress spreading analysis in the real area and frequency characteristics of this bedrock area, frequency progression characteristics. The series of Impulse Seismic Method (ISM) measuring was done for named dynamic parameters determination in this bedrock that was modelled also with determined bedrock dynamic parameters in Visual FEA software, whereby the investigating area was separated into the parts according to the geological profile. The FEM model was created as a circle part plane. Dynamic load was applied as kinematic exciting as point vibration velocity and point vibration acceleration in the middle of the model surface. Measured pavement vibration values induced by the vehicle crossing on highways were the outputs. The distances which the mine vibration cross into and the standard limits that mustn’t be over crossed during the production factory Spinea construction and its operation process are the results.
Highlights
The aim of article is to determine the technical seismicity effect caused by traffic
Technical seismicity and its effects are knew in common as indisposed effect for structures and humans and they are caused by road traffic, rail traffic, construction or by blasting process (Surface Characteristic, 1987; Hanazato et al, 1991)
Analyzed values comparable with all safety standard criteria must be kept with STN EN 1998-1, valid for Slovak Republic (JUHÁSOVÁ, 1985; 1987; STN EN 1998-1)
Summary
The aim of article is to determine the technical seismicity effect caused by traffic. The case study of investigation is production factory in Prešov City in Slovak Republic. There is no way how estimate the distance between the mine of vibration and the structure that is dangerous for this structure. Technical seismicity and its effects are knew in common as indisposed effect for structures and humans and they are caused by road traffic, rail traffic, construction or by blasting process (Surface Characteristic, 1987; Hanazato et al, 1991). The effects are needed to be analysed and determine the technical seismicity effect on the structure. Analyzed values comparable with all safety standard criteria must be kept with STN EN 1998-1, valid for Slovak Republic (JUHÁSOVÁ, 1985; 1987; STN EN 1998-1)
