| In recent years, our country has experienced a rapid development in the construction of railroad highway, water-conservancy and hydropower, mines and city infrastructures. The large-scale construction also created serious problems of high-slope syndrome day by day, and much public attention has been focused on how to solve it. In order both to realize the engineering purposes and safeguard the security of state property and people s life, scholars and engineers in the front of geo-technical engineering have carried out substantial work in scientific research and tests over a long period of tine in the past, and explored out lots of ways, both theoretical and practical, in dealing with landslide prevention and control. Along with the scientific and technological progress, the technology of slide syndrome prevention and control is developing towards compound, light and mechanical ways in treatment. The slope strengthening technology with stress-recovery method using expansion anchors conforms to the development. It will be popularized and spread rapidly due to its specific advantages in treatment of soil slopes slide.This article introduced the cause of slide of artificial slopes and conventional treatment in Pi-shi-hang irrigation area of Qie-ling district, which stands for a watershed between Changjing and Huihe rivers, after introducing slope classification and slope stability analysis, explained the basic theory of stress-recovery method with emphasis on the use of pre-stressed expansion anchors in the treatment of soil slope slide. Through theoretical analysis and project experience, the theoretical and practical value of this new method has been expounded fully in soil slope slide control.
