摘　　要：以南水北调中线驻马店段为研究背景,采用现场调查、工程地质测绘以及钻探手段,查明输水管线沿线地层主要为第四系全新统上段冲湖积层、全新统下段冲湖积层和上更新统冲湖积层。结合设计要求,进一步查明项目施工和运行过程中可能存在地震效应、边坡稳定性、施工排水、水土流失以及泥沙冲刷与淤积等关键技术问题,提出了相应的处理建议。研究可为南水北调中线工程施工和运行过程中可能发生的环境岩土工程问题提供数据支撑。Taking the middle route of south-to-north water diversion project(Zhumadian section)as the research background,on-site investigation,engineering geological surveying and drilling methods were used to determine that the strata along the water transmission pipeline were mainly the quaternary holocene upper section alluvium,the holocene lower section alluvium,and the upper pleistocene alluvium.Based on design requirements,key technical issues that may exist during project construction and operation,such as seismic effects,slope stability,construction drainage,soil erosion,and sediment erosion and sedimentation,and propose corresponding treatment suggestions were further identified.This study can provide data support for the environmental geotechnical problems that may occur during the substantial construction of the middle route of the South-to-North Water Diversion Project.
