| Abstract: | To counter the fractures that the high slopes and weak rocks appear in Beijing-Zhuhai Expressway,the stability of slopes is analyzed by means of a mechanics model of stick-toppling, from which the most dangerous sticks are found. Those are administrated with prestressed anchor rope to improve rock body steady ability and bearing capacity,and to guarantee the whole stability of the project. Calculation procession before and after strengthening, the actual construction method of controlling the quality and construction technology are introduced, it is to give some help for researcher in this field. |
