摘要
结合矿山实际情况,为解决实际工作中对拱形巷道断面测量存在的问题,推导建立了半圆拱、"三分之一"三心拱和"五分之二"三心拱巷道断面简易计算公式,并进行验算。该公式实用性强,可广泛应用于拱形巷道断面的实际测量工作中。
In order to solve the problem of the arched tunnel section measurement in practical work,combined with the actual conditions of mine,this paper derivated and setted up simple formulas about semicircular arch,"1/3" and "2/5" three centered arch roadway section,and checked them.The applicability of these formulas are practical,which can be widely applied in the actual measurement of arched roadway section.
