Abstract


With the rapid development of China 's western region of highway construction , will encounter a lot of high slope . These high slope stability influenced by the strength of the material of the slope , the regional geological conditions , seismic forces and other factors . The traditional methods of analysis of these factors as a setting to consider , there is a larger analytical error , its reliability needs further study . Reliability theory , the stability of the main factors affect highway high slope in the earthquake force to rock slope structural plane shear strength parameters c , φ values ??and seismic acceleration A as the main variable in passing the established coefficient method ( improved Slice Method ) and Monte Carlo simulation based on the reliability of the calculation model of slope stability ; analysis of the distribution of c, φ values ??and seismic acceleration a type sampling using the Monte Carlo simulation method simulation to study the reliability of the calculation method for the the earthquake force high road slope stability . Shiyan - Tianshui Expressway in Shaanxi Han - Shaanxi and Gansu sector in the Middle East as the basis , using the Monte Carlo simulation of two typical high slope c φ value and the seismic acceleration A value analysis , using MATLAB computing software entities engineering slope stability reliability were calculated , and the transfer coefficient method to calculate the safety factor of the slope , to verify the reliability analysis of the correctness of the model and calculation method established .
