南水北调中线膨胀土渠道安全监测成果分析

Safety monitoring data analysis of expansive soil main canal in Middle Route of South-to-North Water Diversion Project

为给膨胀土变形机理研究提供准确的监测数据,在南水北调中线工程膨胀土渠道设置了试验区,选取多个监测断面,结合渠道结构布置监测项目,对渠坡和渠基进行安全监测。对渠道施工期的安全监测成果分析表明,渠道的外部变形、内部变形、应力应变、渗流渗压等变化规律基本正常。监测成果可为膨胀土变形机理研究提供数据支撑。

In order to provide accurate monitoring data for studying the mechanism of expansive soil deformation,multiple sections were selected in the experimental zone that were arranged along the expansive soil canal of Middle Route Project of South-to- North Water Diversion Project The safety monitoring of canal slope and foundation is conducted with consideration of different canal structures. The monitoring results during canal construction period show that the change laws of canal parameters such as external and internal deformation,stress- stain and seepage pressure are normal.
