DETERMINATION IN FIELD CONDITIONS OF THE CURVES SECTIONS RADIUS OF THE TECHNOLOGICAL AUTOMOBILE ROADS FOR TIMBER AND FORESTRY PURPOSE

Abstract

The problem of technical accounting and certification of technological roads networks of Ukrainian forestry enterprises was considered. The need for the first stage of determining the actual parameters of existing forest roads in the field was noted, since not all industry enterprises need reliable technical information. Also, with a general problem, its component part is distinguished, due to the need to quickly determine the characteristics of the alignment plans of existing forest roads, in particular, the radius of curvature of the sections curves.

In the analyzing process of the research scientific results publication, it was found that in related industries a number of methods have been tested for determining the radius of horizontal curves road sections that have certain advantages and disadvantages in specific natural working conditions and various indicators of accuracy, cost, safety and ease of use.

It is recommended to use the chord angle fixing method to determine the radius of forest road curves sections, which is accurate enough for engineering calculations and does not require the use of special equipment. Using the proposed method and the measuring instrument available at the enterprise, experimental studies were carried out. Based on the experience gained, recommendations for rational organization of work in the field were formed.
