Study on Differences in Limit State Design Methods for Slopes in China and Europe
Aiming at the slope limit state design problem,according to the current geotechnical design standards in China and Europe,the limit state design standard system,slope reliability analysis method and slope limit state design method are compared and analyzed.The findings reveal that the mechanical and mathematical principles underlying soil and rock engineering design are largely consistent between China and Europe.However,notable disparities exist in the engineering design frameworks outlined in the respective standards.Concerning the formulation of partial factors for the slope limit state method,China's adoption of the Level Ⅱ method appears more progressive than Europe's reliance on historical empirical methods.Moreover,differences in the calculation methods for slope stability between China and Europe render a direct comparison of limit state design examples for railway slopes impractical.
