  • In order to improve the stability of upper slanting waterproof highway loess dam-like embankment, earthquake effect on slope stability was analyzed, the calculation formula of slope stability coefficient was deduced by introducing earthquake parameter and using simplified Bishop method, the water pressure action and mechanical balance principle of the embankment were studied, its whole stability judgment qualification was got.The calculation result of slope stability shows that earthquake effect on slope stability is great, the minimal error of slope stability coefficient is 0.1 (earthquake intensity is 7°) in the conditions of earthquake and no earthquake, relative to the slippery points out of slope bottom and on slope, the slope stability coefficient of the former is less than that of the latter, the stability coefficient value that slope is immersed in water is less than the value that slope is not immersed in water, the slippery point position, immersed state and earthquake effect must be considered when the stability is computed.The whole stability calculation result of the embankment shows that the embankment is safe when ditch gradient is 2.872%, the embankment is ruin when ditch gradient is 10.000%, so loess dam-like embankment must be built on placid ditch.
