【摘要】 南水北调中线工程北京段工程地质勘察工作历经十几年,其间经过一次由明渠改为管道的重大设计方案调整,随着设计方案的调整与建筑物的变化,相继进行了相应设计阶段的地质勘察工作。本文总结了本工程历经十几年的工程地质勘察工作的实践与经验,尤其是对施工中遇到的工程地质问题的处理以及施工开挖对前期勘察成果的验证作了比较详细的介绍。更多还原

【Abstract】 In the construction of the Middle Route South-to-North Water Transfer Project,the engineering geological investigation of Beijing Section has been carried out for more than 10 years.During that time,a major design adjustment of adopting pipeline instead of open channel occurred.As the adjustment of designing plan and the changes of buildings,geological investigation work has been developed successively on corresponding design phases.In this paper,the practices and experiences of geological investigation work done in the past years construction is summarized.Especially,treatments to geological engineering problems and verifications between excavation construction and the early investigation results have been introduced in detail.更多还原
