Taking a large number of expressway slopes in Chongqing as examples,the method of artificial neural network is studied and used in prediction.

4GHz ZigBee communication protocol, a new system scheme is designed on real-time stability-monitoring of expressway slope.

Temporal changes in plant communities and soil properties,one to two years after vegetation establishment along the Hu-Ji Highway slopes were investigated to assess the process and mechanism of soil fertility and vegetation restoration.

Application of anisotropic damage anchorage model in a large sized highway landslide reinforcement;

The formation and mechanism of an expansive soil highway landslide;

With an example of expansive soil highway landslide in Sta.

Dynamical analysis on the whole process of acute colliding high speed landslide;

A new method for forecasting the severity of activity of high speed landslides is presented, in which the variations in the deformation and speed of the sliding mass can be considered simultaneously with the conversion and dissipation of energy.

Based on the analysis on the formation mechanism and characters of motion and accumulation for high speed landslide, the speed and deformation of the sliding mass are of inhomogeneity, and its motion process is in company with the accumulation, release and loss of strain energy.

Many serious disasters are resulted from high-speed landslides,which take huge energy and high speed as their characteristics.

In the paper the high-speed landslides of Guizhou are related by the actual examples, the existence of the high-speed landslides in Guizhou is confirmed and their identified ways are accounted.
