砖板衬里中的环形拱圈设计

Design of Arch and Ring in Brick lining

论述了砖板衬里中常见的环形拱、圈配砌计算问题，指出在采用通用计算公式计算时，部分尺寸区域会出现计算出的结果在实际中无法施工的现象，找出了通用计算法中存在的问题，结合实际经验提供三种不同的解决方法。

Abstract The common problems with arrangement calculation of arch and ring in brick lining are discussed.Its pointed out that the calculated results from general formulas cannt be used in practical construction in some areas.The problems in general calculus are found out and three different resolution methods are given on the basis of practical experience.
