    Abstract
  • Taking landslide treatment of an expressway in Huadu, Guangzhou as an example, the instability and deformation mechanism of bedding cutting slope with soft interlayer and multistage sliding surface was analyzed, and the stable state of slope was determined. On the basis of the emergency treatment of gravel back pressure, combined with the back pressure body, limit equilibrium method and finite element method were used to analyze and calculate. Considering all kinds of restraining factors, the comprehensive treatment measures of prestressed anchor cable and circular anti-slip pile were adopted. According to the monitoring situation during construction and operation, the landslide treatment is effective.
