摘要
膨胀土地区的渠道常常发生滑坡。给工程的安全运用带来很大影响。为了解决这个问题，对膨胀土渠坡滑动进行监测，并对监测资料进行分析，以弄清滑动过程的机理和应力变形的变化过程很有意义。本文叙述了在一段选定的渠道上进行了专门的渠坡滑动试验，在土体中埋设了各种仪器监测它的应力和变形发展过程，得出了有意义的成果。
The sliding of canal slope is rather often in expansive soil area. To clarify the machanism of the sliding, a test section in Diaonan Irrigation canal was chosem. Many instruments for measuring the stress、deformation、ground temperature ans soil moisture were installed before canal excavated. As the excavation work carrying out, a sliding happened. Based on the analysis of observed data. some significant understanding was obtained.
