【摘要】 基于突变级数理论,对边坡地震的稳定性提出了一种综合评价方法。首先对边坡地震稳定性的评价目标进行多层次矛盾分解,并对数据归一化处理,利用突变理论与模糊数学相结合产生突变模糊隶属函数,由归一公式进行综合量化运算,得到总的隶属函数,从而进行边坡地震稳定性的分析评价。对16个典型的地震边坡作为预测样本进行了评价研究,并将得到的预测结果与灰色聚类法、综合指标法预测结果以及与边坡的实际震害程度进行比较。研究结果表明,突变级数法成功率高、客观性强,为边坡地震稳定性的研究提供了一条新思路。更多还原

【Abstract】 Based on catastrophe progression theory,an integrative evaluation technique was presented to predict the seismic stability of slope in this paper.The complex index system of the seismic stability of slope was decomposed by a multi-level objective method.Then according to the normalization formula and the fuzzy subject function which was produced by the combination of catastrophe theory and fuzzy math,a recursive calculation was carried out to get a catastrophic affiliated functional value,which can be used to evaluate the seismic stability of slope.16 actual samples were used to verify the effectiveness of this technique.Compared with grey clustering method and comprehensive index method,the results from this technique show that catastrophe progression method has a practical value in evaluating the stability of slope during earthquake.This paper provides a new way for evaluation on seismic stability of slopes.更多还原
