This article focuses on the application of lattice anchor system in high slope protection. According to the engineering geological characteristics of the slope of the site, combined with the requirements of the layout of the slope of the site, the slope is permanently supported by the combined support system of lattice anchor rods, nets, and soil spray. The example takes the slope under the arc failure mode as the research object to carry out the parameter design calculation, and conducts real-time monitoring during and after the construction. ...
