Deformations of bridge support on frozen taliks


Keywords: Permafrost, talik, coastal support, deformations, freezing.



On an example of deformations of the bridge through the river Shuchya it is considered not analyzed earlier in practice bridge building a case of power interaction of closed local files of the frozen ground formed round support from hollow metal pipes. The analysis of sequence of formation of frozen files in a zone of the support constructed in taliks with their subsequent freezing, and character of deformations in coats in the course of their freezing is given. Possible directions in working out of measures on prevention of such deformations are considered.

Reliable straightening-tamping machines


Keywords: railway track, integrated indicators of reliability, straightening - tamping  machine, track machines



In this article the developed and implemented a model that allows us to estimate an integrated performance reliability of liner- tamping - straightening machines at specific sites of railway track based on actual field observations during the operation of the straightening - tamping - straightening machines VPR- 02 and VPRS - 02 per between 2001 and 2012 at the site of the West - Siberian infrastructure Directorate - the structural unit of the Central Directorate of infrastructure - branch of JSC " Russian Railways " and annual reporting documentation management operation and maintenance of machinery for travel . Partially processed information is obtained based on the results of field observations of the process of machine operation VPRS -02 , which is located at the site of the Siberian State University of Railways in 2007 as part of laboratory work in various academic disciplines : "Apparatus and bases of calculation of track machines ", " travel machine ", " drives track machines "," Operation Track Machine " conducted on the machine.
