【 摘 要 】

In order to study the influence of initial gravity field on slope stability analysis under the conditions of slope height, slope angle and soil bulk density, some slope examples are analyzed by combining finite element method and shear strength reduction method. The calculation results show that the initial gravity field has a great influence on the slope displacement and shear stress. But this effect has nothing to do with the slope height, slope angle or soil bulk density, but has little effect on the slope stability safety factor. The relevant results can be used by engineers and technicians for reference in slope design.
