摘　　要：为进一步提高国内铁路建设项目生态环境保护管理水平,解决涉及环境敏感区的铁路隧道施工期废水处理中存在的一些问题,采用分析总结的方法,首先按周边水体敏感性类别及环保要求分析确定施工期废水处理站的设置原则;其次通过分析目前处理规模常用计算方法的缺陷与不足,提出应在隧道实施过程中结合施工组织实行清污分流措施,并针对顺坡单线、双线隧道及逆坡隧道的具体情况探讨了较为合理的清污分流措施,基于此提出一种新的计算方法。新计算方法可根据隧道洞身单位长度、正常涌水量与施工未衬砌段长度计算施工废水处理规模,适用于大部分常规地质条件。In order to advance the ecological environment management of domestic railway construction,and in order to solve some problems existing in wastewater treatment during railway tunnel construction involving environmentally sensitive areas,the author adopts the method of analysis and summary.Firstly,the setting principle wastewater treatment station of railway tunnel during construction is analyzed and determined according to the sensitivity categories of surrounding water bodies and environmental protection requirements;secondly through analyzing disadvantage of the traditional calculation method,the author provides water-wastewater diversion method in the condition of slope single track tunnel,slope double track tunnel and adverse slope tunnel,and provides a new calculation method based on this.The conclusion is:The new calculation method is calculated according to normal water inflow per unit length of tunnel trunk and length of unlined section under construction,which is applicable to most conventional geological conditions.
