Xindacheng second-line tunnel was close to the existing line tunnel.
新大成二线隧道紧临既有线隧道,为确保既有线隧道和行车安全,采取了导坑超前三步开挖,中空大直径直眼掏槽,炮眼水压爆破和实时爆破振动监测等技术措施,安全完成了工程,全段施工进度达每月59 m。
Research methods:Take the double-track tunnel in the Lanzhou-Wunan for example,the relation graph of train speed and maximum pressure has been simulated and figured out with the formula.
研究目的:通过计算,分析我国双线隧道中存在的瞬变压力问题,并提出相应的缓解措施。
