无轨运输隧道施工辅助斜井型式探讨

摘要

为解决隧道施工辅助斜井单、双车道选择以及斜井轮廓尺寸方面的问题，通过对行车限定速度、错车时车辆通过情况进行模拟，以数学推导的方法，分析单、双车道的通过能力，研究斜井内的断面布置。认为单、双车道斜井的通过能力相差极大，当通过斜井开辟隧道施工工作面较多，计算施工高峰期总车流量大于单车道斜井最大通过能力时必须采用双车道；同时通过对单、双车道断面布置中的车辆外形、各种间隙、人行道、管路、水沟等尺寸的研究，提出了单、双线斜井轮廓尺寸。%The situation of vehicle passed under the conditions of limited vehicle running speed and vehicle passing is simulated.The transportation capacity of single-lane and twin-lane are analyzed by means of mathematical deduction method.The layout of the inclined shaft cross-section is analyzed.The results show that:1 )The vehicle passing capacity of twin-lane inclined shaft is far larger than that of single-lane inclined shaft.2 )The cross-section size of single-lane inclined shaft and that of twin-lane inclined shaft are proposed by making analysis on relevant parameters.
