【摘要】：為研究主線連通性在時間維度上的變化對高速公路施工事故救援路線選擇的影響,分析影響救援路線管理單元劃分的因素,提出影響主線連通性的主要控制工程選擇標準及其施工進度的時間參數序列。引入時間參數,把高速公路建設項目線性實體分為周期點元、周期線元、即時點元、即時線元進行數學描述,建立以控制工程施工進度為變量的動態(tài)管理單元劃分模型并基于路阻函數建立路網優(yōu)化模型,實現對應急救援路網的動態(tài)管理。研究成果在重慶沿江高速公路應用表明,當時間參數分別小于14,20個月和大于36個月時,對比優(yōu)化前應急救援路網,救援時間分別縮短約6,26和37 min,提高了救援效率。
[Abstract]:In order to study the influence of the change of mainline connectivity in time dimension on the choice of rescue route in expressway construction accident, the factors influencing the division of rescue route management unit are analyzed. The main criteria for controlling project selection and the time series of construction progress are presented. Introducing time parameter, the linear entity of expressway construction project is divided into periodic point element, periodic line element, instant point element and instant line element. The dynamic management unit partition model based on the control of construction progress is established and the road network optimization model is established based on the road resistance function to realize the dynamic management of the emergency rescue network. The application of the research results to the expressway along the Yangtze River in Chongqing shows that when the time parameters are less than 14, 20 months and more than 36 months, the rescue time is reduced by about 626 and 37 min, respectively, and the rescue efficiency is improved by comparing the emergency rescue network before optimization.
