Based on the analyse and evaluation of some destroyed models of bedded rock and massive rock and cataclastic rock,which is in the high-level road in the mountainous area,and combined with the engineering examples,the author put forward synthetic preventing measures,emphasized on the discussing on new methods,planting grass and anchor-shotcrete.

The anchor sprayed concrete technique has widely come into use in the engineering construction.

Study on taking shotcrete precautions against gateway fire in fully mechanized mining with sublevel caving;

Application of anchor bar and shotcrete method in the protection engineering to side slop in Luo-Ning Expressway;

To measure thickness of sprayed concrete by neutron scattering method;

On the monitor experience of the deep foundation pit support of the Hua-du Commercial Center in Guangzhou,the paper has probed the constructing quality of the foundation pit of deep agitation keg and anchoring-shotcreting net.
