汕头至汕尾铁路东都村隧道局部方案研究

Research on Partial Scheme of Dongdu Village Tunnel of Shantou-Shanwei Railway

以汕头至汕尾铁路东都村隧道为基础,针对东都村隧道浅埋偏压严重、施工风险高、工程投资大等问题,结合地质、规划、环保等因素,分别研究了南移增加隧道埋深方案、北移取消隧道方案以及原位抬高路基方案、桩基护拱暗挖方案.通过对各方案的时间成本、工程可实施性、安全可靠性、经济合理性等方面的分析,最终选出了推荐方案.其思路可供工程总承包方案研究工作参考.

Based on Dongdu Village Tunnel of Shantou-Shanwei Railway,aiming at the problems of serious shallow buried bias,high construction risk and large project investment of Dongdu Village Tunnel,and combined with geological,planning,environmental protection and other factors,the paper respectively studies the scheme of increasing tunnel buried depth by moving south,the scheme of canceling tunnel by moving north,the scheme of raising subgrade in situ,and the scheme of protecting arch by pile foundation.Based on the analysis of the time cost,project implementability,safety and reliability,economic rationality and other aspects of each scheme,the recommended scheme is finally selected,which can provide reference for the research work of the general contracting scheme of the project.
