摘要
南水北调中线总干渠与众多的河流和沟渠相交切割,形成了左岸排水下穿总干渠的"楼中楼"式小近距交叉工程态势。它们将共处于同一个错综复杂的渗流场内,成为区域渗控设防难点之一,值得进一步探讨。文章在指出当前工程实施中一些值得注意的问题的同时,提出了一种比较易于实现渗控的工程措施或可供参考。
he primary channel of the Middle Line of the South-to-North Water Transfer Project traverses some rivers and ditches, so it forms a state of ＂double deck＂ type and close to crossing project for drainage of the left bank. They will stand in the complex seepage flow field that is difficult to resolve. The author not only points out some noticeable things of current project, but also puts forward some measures for solving the matter.
