In allusion of an engineering case of the improvement of Xiangjiapo cut slope of Yu-Qian highway

this paper firstly describes the sliding of the slope in early stage and unsuccessful controlling works and then it ues the measuring results of ground surface monitor in connexion with detailed geological exploration to judge accuraltely the property and the mechanism of the sliding disater of the cut slope. And on this basis

this paper sums up the reasons of previous unsuccessful improvement and then makes the stability analysis in which the sliding mass and previous supporting works are considered to be a compound body. Finally

the paper draws up a comprehensive multiple-way controlling scheme in which temporary and permanent control of the cut slope are jointed organicly. It is a comprehensive control measure for cut slope sliding

being reliable

rational and economical.
