Abstract (English):
Osnovnym nedostatkom derevyannyh shpal yavlyaetsya malyy srok sluzhby po sravneniyu so shpalami, izgotovlennymi iz drugih materialov. Bol'shoe vliyanie na srok sluzhby i kachestvo derevyannyh shpal okazyvayut poroda drevesiny i kachestvo propitki antisepticheskimi sostavami. Naibol'shee rasprostranenie pri proizvodstve shpal poluchila drevesina sosny. V nastoyaschee vremya zapasy dannoy drevesnoy porody v evropeyskoy chasti RF sil'no istoscheny i na rynke prisutstvuet nehvatka syr'ya, udovletvoryayuschego trebovaniyam standartov, pred'yavlyaemym k lesomaterialam, iduschim na izgotovlenie shpal. Odnim iz resheniy dannoy problemy yavlyaetsya vozmozhnost' rasshireniya porodnogo sostava drevesnyh porod, ispol'zuemyh dlya izgotovleniya shpal. V nastoyaschee vremya preobladayuschey gruppoy porod v Central'nom Federal'nom okruge RF yavlyayutsya myagkie listvennye porody. Ishodya iz zapasa drevesnyh porod i fiziko-mehanicheskih pokazateley, celesoobrazno dlya proizvodstva shpal ispol'zovat' drevesinu berezy. Nedostatkom dannoy porody yavlyaetsya nevysokaya biologicheskaya stoykost', nedostatochnaya plotnost'. Povysit' plotnost' drevesiny berezy mozhno za schet pressovaniya. Dlya realizacii tehnologii pressovaniya drevesiny neobhodimy svedeniya o haraktere ishodnogo syr'ya. Drevesina yavlyaetsya biologicheskim materialom, svoystva kotorogo izmenyayutsya v stvole dereva. V rezul'tate vypolnennogo issledovaniya ustanovleno izmenenie vlazhnosti i plotnosti drevesiny po vysote stvola dereva, kotoraya sostavlyaet dlya drevesiny berezy 2.11 % na kazhdyy metr vysoty stvola. Na osnovanii etih dannyh dlya komlevoy, sredney i vershinnoy chastey stvola i s uchetom trebuemoy konechnoy plotnosti pressovannoy drevesiny dlya proizvodstva shpal byla rasschitana nachal'naya tolschina brus'ev i neobhodimaya stepen' ih pressovaniya. Eto pozvolilo poluchit' odnorodnuyu plotnost' pressovannoy drevesiny shpal i snizit' rashod syr'ya dlya proizvodstva shpal'nogo brusa s uchetom ego mestopolozheniya v stvole dereva.
