南水北调中线工程潮河段渠道工程线路长,地质条件复杂,渠道沿线穿越地震液化段累计长度约占渠线总长的67%,地震液化对工程的安全运行产生严重危害。文章就潮河段渠道设计为例,介绍总干渠饱和砂土地震液化处理措施。
The mid-route of the South-to-North Water Diversion Project has a long channel with a complex geological condition. The cumulative length of the liquefaction section along the canal line accounts for about 67% of the total length of the canal line. Earthquake liquefaction poses a serious hazard to the safe operation of the project. In this paper, the channel design of tidal reach is taken as an example to introduce the seismic liquefaction measures of the saturated sand in the main canal.
