| Abstract: | Through the analysis of character of mechanic model of pre-stress anchored anti-slide pile that people are accustomed to u-sing at present, some deficiencies are found out and the improved distribution function of the landslide-thrust and the resistance of soil or rock are provided with a chart, the working principle of pre-stressed anchor and it's use in the mechanic model building process also is studied. The improved method for mechanic model building is presented and the result of new method is compared with the result of old one based on the use of practical engineering. The rationality of improved method also is discussed. |
