一、引言在黄土地区修建渠道,常因黄土的变形,而使渠道边坡遭到破坏。为了探讨在黄土中修建渠道之边坡稳定问题,我们在进行引洮总千渠隴西地段工程地质测量工作的同时,曾先后对引洮总干渠古城至六盤山一段地区,进行了滑坡的调查工作。在调查工作中,我们除了向当地羣众访问滑坡的一般情况外,并实测了滑坡特征,进行了素描工作。因时间所限,仅沿线调查了甘余个较大的滑坡,其中 I. INTRODUCTION The construction of channels in the loess area often causes the slope of the channel to be damaged due to the deformation of the loess. In order to explore the stability of the slopes in the construction of loess channel, we carried out the survey on landslides in the section of Gucheng to Liupanshan which led to the main canal of the Loess Plateau. . In the course of our investigation, apart from interviewing the general public about landslide problems, we measured the landslide characteristics and carried out sketches. Due to time constraints, only a few more landslides were surveyed along the route, of which,
