基于西安地裂缝轨道框架板的方案研究

Study on the scheme of the track frame plate in Xi'an

地裂缝的活动将对地铁施工和安全运营产生不利影响,如何保证地裂缝活动作用下地铁的正常运行,是地铁设计过程中必须解决的问题,提出一种新的轨道框架板的调整方案,采用"主动沉降"的方式来适应地裂缝沉降,不仅适用于解决暗挖法施工困难区域的施工,且能根据实际情况减少矿山法区间长度。

Ground fissure activities will be able to produce adverse effect to the subway construction and safety operation,how to ensure the normal running of ground fissure activity under the action of the subway,is the problem must be solved in the process of design. In this paper,a new adjustment scheme of the rail frame plate is proposed,which is not only suitable for the construction of the difficult area of the excavation,but also can reduce the length of the mining method according to the actual situation. The method of＂active settlement＂is used to adjust the settlement of ground fissures,which can significantly reduce the project implementation difficulty and save the project investment.
