摘要
在对建筑的工程地质条件等分析的基础上,对基坑开挖土方放坡的稳定性进行了定性分析和定量计算,运用条分法和有限元ANSYS分别对该放坡天然状态、饱和状态进行了稳定性计算,两种计算方法结果均表明:天然状态下,放坡处于稳定状态,饱水状态下,放坡处于不稳定状态,与定性分析和实际情况相吻合。
Based on the analysis of the geological condition of the construction project, the stability of the foundation pit excavation earthwork step-slope is analyzed qualitatively and calculated quantitatively, the stability calculation of the step-slope＇s natural state and saturation state is got respectively based on the slice method and finite element ANSYS. The results of this two calculating methods all show that the step-slope is in stability state in natural state and in non-stability state in saturation state, which is accordance with qualitative analysis and practice situation.
