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.
