摘    要:南水北调中线工程(京石段)自2005年开工以来,在施工过程中遇到诸多问题,其中之一就是部分渠段合格填筑土料的严重不足,从而制约了工程进度,而其开挖弃土多为中细砂,若能采取措施利用中细砂筑堤,充分利用渠道的弃土土料,就地取材,不仅能减少占用耕地,而且也能缩短工期,本文就改性中细砂的一些方案进行了室内试验研究。

关 键 词:改性土筑堤 试验研究 南水北调中线工程

Abstract:Many problems occurred during construction since Beijing-Shijiazhuang section on the Mid-route of the South-to-North Water Transfer Project started in 2005. One of them is the lack of eligible soil which has influenced the schedule,and the excavatin soil is mostly made up of fine sand and medium sand, therefore if we can use them for the embankment the required infield will reduce and the time of completion will be ahead. we studied the alternative of modified fine-medium sand throught comparative test.
Keywords:embankrnent of modified soil ltest study  Mid-route of the South-to-North Water Transfer Project
