Slope stability and reliability of the stochastic finite element analysis
Reliability index of slope stability calculations Table2Thecalculated slander e | ofdindex Lu oftheslopestatrait, / byperturbationstocha + ac note ; 1 refers to the c, modeled as random , 2 refer to c, seen from the above results . When the c, 'P is modeled as random . Reliability index increased by 30 % of the project , in line with the actual situation, because the distribution parameters for a single random variable simulation will overestimate their variability ,
Ralph Lauren Preisen, calculation of the variability to be increased , or the reliability index to be reduced; otherwise reliable degree index will increase . Consider c, the negative correlation , the reliability index to be larger ,
Billig Ralph Lauren Polos, but the magnitude of changes is not very significant. Calculated using stochastic finite element slope stability of the overall reliability index a = 1.127-1.558 , relative to the upper structure of the target reliability index or light -based stable reliability index lower , with the possibility of greater instability . while the uncertainty analysis method = 1.185 . to meet the stability requirements; but the reality is , in the summer dry season, the slope failure , resulting in a wide range of circular sliding , sliding surface is dry , no signs of permanent role this paper the results reflect this reality. 6 Conclusion probability in geotechnical engineering analysis ,
Ralph Lauren Polos Human bird flu treatment progra, largely through a single random variable model , with one-dimensional Airport models and stochastic finite element models of three phases , stochastic finite element model of the biggest advantages of the finite element analysis techniques and reliability combine to consider a variety of random factors affect the results of the calculation ,
scarpe Hogan uomo, the results can be more reliable in slope stability analysis,
Billig Ralph Lauren, soil- parameter variability, correlation and probability distribution factors have a greater impact on the reliability index , must obtain enough statistical information and in-depth study of slope stability stochastic finite element analysis is still in the research and development into , this is exploratory research , reliability analysis of slope stability for the future have a certain reference value .
