- Consideration in the long - term planning of mrt routes . other downsides to the single tunneling method are that it requires longer construction time , and that two break throughs from the tunnel to the work shaft involve a higher construction risk
（一）本局规划手册所引用之消防逃生设计大多以美国国家消防协会（ national fire protection association ， nfpa ）中针对定轨运输系统设计之nfpa - 130规范为蓝本，再配合本地建筑法规及消防法令，故有必要重新检讨法令适用问题及如何配合修订相关法规。 - Being lacking of understanding of behaviors of circular working shaft , the paper proposed theory about ring - beam ' s load - distribution calculations and analyzed the structural behavior of circular working shaft ( cws ) by the numbers from the standpoint of properties of structural style and stress incorporated with thoughts of shared load introduced to research of cws . first , regarding cws as structure of series of hypothetic horizontal circular rings and vertical beams , and considering cws ' s formation and development , the paper proposed load - distribution thoughts to solve cws ' s calculations . ring - beam calculation theory was put up and software cbtlmp1 . 0 was worked out based on the conditions of external applied load shared by rings and beams , and of deformation conformity
首先，本文提出用分载思想解决圆形工作井结构的计算分析问题，将圆形工作井结构看成是由一系列的假想的水平圆环和竖直梁组成的结构，考虑工作井形成过程及形成阶段与项进阶段的连续性，根据某一时刻相对于上一时刻外载增量由环与梁分担、环与梁在交叉处变位增量一致的条件将环计算理论与梁计算理论结合起来，据此建立了环?梁分载计算理论并研制了环?梁分载计算分析软件cbtlmpv1 . 0 。
