摘　　要：盐泰锡常宜铁路北起盐城,经泰州、无锡、常州,南止于宜兴。该线路是策应“交通强国”国家战略,推进长三角城市群区域一体化发展的需要。本文以线路走向中油田为切入点,利用数值仿真方法建立了油气开采沉降模型、爆炸波伤害效应模型和爆炸火球伤害效应模型,结果表明:(1)研究区最大沉降量为2.9 mm;盐城1号井喷时发生爆炸的安全距离为119 m;发生火灾时安全距离为141 m;(2)结合相关规范,综合得出拟建高速铁路与油气井最小安全距离不小于150 m;(3)对盐城至泰州段线路走向方案进行选线研究,将整体线路走向及卤汀河局部方案进行比选,综合确定了科学、经济、合理的线路方案,满足了铁路设计的总体目标。Yancheng-Yixing High-speed Railway starts from Yancheng,passing through Taizhou,Wuxi and Changzhou,and ends at Yixing.This line is designed to meet the national strategy of a powerful transportation country to promote the regional integrated development of the Yangtze River Delta urban agglomeration.This paper focuses on oil field where the route passing through and uses numerical simulation methods to establish models for oil and gas extraction induced subsidence,explosion wave damage effect model,and explosion fireball damage effect model.The results show that:(1)The maximum subsidence in the study area is 2.9 mm.The safe distance for an explosion during the Yancheng No.1 blowout is 119 m.The safe distance in case of fire is 141 m.(2)Combined with relevant regulations,it is concluded that the minimum safe distance between the proposed high-speed railway and oil and gas Wells is no less than 150 m.(3)Through studying route selection for the Yancheng-Taizhou section,comparing the overall route direction with the partial plan of Luting River,a scientific,economic,and reasonable route plan is finalized,which meets the overall goal of railway design.
