Kubara Umuyaga Uhumeka no Guhitamo Ibikoresho mu Kubaka Umuyoboro (2)

2. Kubara ingano yumwuka ukenewe mukubaka tunnel

Ibintu bigena ingano yumwuka usabwa mubikorwa byo kubaka umuyoboro harimo: umubare ntarengwa wabantu bakorera muri tunnel icyarimwe;umubare ntarengwa w’ibisasu bikoreshwa muguturika kimwe: umuvuduko ntarengwa wumuyaga ugaragara muri tunnel: gusohoka kwimyuka yubumara kandi yangiza nka gaze na monoxyde de carbone, numubare wa moteri yaka imbere ikoreshwa mumurongo Tegereza.

2.1 Kubara ingano yumwuka ukurikije umwuka mwiza usabwa numubare ntarengwa wabantu bakora muri tunnel icyarimwe
Q = 4N (1)
aho:
Ikibazo - ingano yumwuka isabwa muri tunnel;m³/ min;
4 - Umubare ntarengwa wumwuka ugomba gutangwa kumuntu kumunota; m³/ min • umuntu
N - Umubare ntarengwa wabantu muri tunnel icyarimwe (harimo kuyobora ubwubatsi);abantu.

2.2 Kubarwa ukurikije ingano y’ibisasu
Q = 25A (2)
aho:
25 - Umubare ntarengwa w’ikirere usabwa ku munota kugirango ugabanye gaze yangiza iterwa no guturika kwa buri kilo cy’ibisasu kugeza munsi y’ibishobora kwemerwa mu gihe cyagenwe;m³/ min • kg.

A - Umubare ntarengwa wibisasu bisabwa kugirango iturika rimwe, kg.

2.3 Kubarwa ukurikije umuvuduko muto wumuyaga ugaragara muri tunnel

Q≥V_{min •}S (3)

aho:
V_min- umuvuduko ntarengwa wumuyaga ugaragara muri tunnel;m / min.
S - agace ntarengwa kambukiranya igice cyubwubatsi;m².

2.4 Kubarwa ukurikije ibisohoka imyuka yubumara kandi yangiza (gaze, dioxyde de carbone, nibindi)

Q = 100 • q · k (4)

aho:

100 - Coefficient yabonetse ukurikije amabwiriza (gaze, karuboni ya dioxyde de carbone isohoka mumaso ya tunnel, imyuka ya dioxyde de carbone ntabwo iri hejuru ya 1%).

q - isohoka ryuzuye rya gaze yuburozi kandi yangiza mumurongo, m³/ min.Ukurikije impuzandengo yagaciro yimibare yapimwe.

k - coeffisente idahwitse ya gaze yuburozi kandi yangiza isohoka mumurongo.Ni igipimo cyinshi cyo gushing ingano yo kugereranya gushing ingano, iboneka mubibare nyabyo byo gupima.Mubisanzwe hagati ya 1.5 na 2.0.

Nyuma yo kubara ukurikije uburyo bune bwavuzwe haruguru, hitamo imwe ifite Q nini nini nkigiciro cyumwuka usabwa kugirango umuyaga wubatswe muri tunnel, hanyuma uhitemo ibikoresho byo guhumeka ukurikije agaciro.Byongeye kandi, umubare wimashini zitwika imbere nibikoresho bikoreshwa muri tunnel bigomba gusuzumwa, kandi ingano yumuyaga igomba kongerwa muburyo bukwiye.
