摘　　要：从环境科学的角度对中国安能集团第三工程局有限公司成都分公司在进行类似西气东输工程的隧道施工排水过程中水质变化及其环境影响进行了初步探讨。研究指出,隧道施工排水活动显著改变了排水区域的水质参数,包括但不限于pH值的变化、悬浮物的增加以及重金属的潜在释放。此外,排水对地下水流动模式造成的改变可能对周边生态系统和地下水资源产生长远影响。针对上述问题,提出了一系列施工排水管理措施,包括水质处理、水量控制、生态保护和监测预警系统的建立,以及预防和应急响应机制的制定,旨在减少环境影响并促进施工活动与环境保护的协调发展。通过综合性的管理措施,可有效缓解施工排水对环境的不良影响,保护水资源和生态环境,同时确保工程建设的顺利进行。This article preliminarily explores water quality changes and their environmental impacts in the drainage process of the Chengdu Branch of China Anneng Group Third Engineering Bureau Co.,Ltd.constructing tunnels similar to the West-East Gas Transmission Project from the perspective of environmental science.Research shows that the activities of tunnel construction drainage significantly alter the water quality parameters of the drainage area,including but not limited to changes in pH value,increase in suspended solids and the potential release of heavy metals.In addition,the changes of groundwater flow patterns caused by drainage may have long-term impacts on surrounding ecosystems and groundwater resources.In order to solve above issues,the article proposes a series of management measures for construction drainage,including water quality treatment,water quantity control,ecologi⁃cal protection,the establishment of monitoring and early-warning systems,and the development of prevention and emergency response mechanisms,aimed at reducing environmental impacts and promoting the coordinated develop⁃ment of construction activities and environmental protection.Through comprehensive management measures,the adverse effects of construction drainage on the environment can be effectively alleviated,water resources and the ecological environment can be protected,and the smooth progress of engineering construction can be ensured.
