摘要
在山区高速铁路建设中,不可避免地会出现深路堑,如果方案选择不合理,则会造成当地环境的破坏,导致地质灾害频发,直接威胁到高铁运营的安全。因此,正确、合理地选用深路堑和隧道方案,显得非常重要。文章主要从地质条件、环境影响、施工难度、综合经济成本、运营安全等五个方面,比较研究了深路堑与隧道选用的适用性,并提出了方案选择的建议。
It is inevitable for the construction of high-speed railway to encounter deep cutting in mountain areas.And it is easy to damage the local environment with improper scheme and result in frequent geological hazard directly threatening the safety of railway operation.Thus it is important to choose a reasonable alternative of deep cutting or tunnel.The applicability of selecting deep cutting and tunnel are compared and studied in terms of geological condition,environmental impact,construction difficulty,comprehensive economic cost and operation safety,and some suggestions concerning this are put forward.
