【摘要】：為準(zhǔn)確評(píng)價(jià)巖土邊坡地震穩(wěn)定性,建立基于直覺(jué)模糊集逼近理想解排序(TOPSIS)法的邊坡地震穩(wěn)定性評(píng)價(jià)模型。首先綜合考慮定量與定性指標(biāo),選取巖土體特征、新構(gòu)造運(yùn)動(dòng)特性、坡高、坡角、年降水量、場(chǎng)地地震烈度等6個(gè)因素為邊坡地震穩(wěn)定性評(píng)價(jià)指標(biāo);然后針對(duì)定性指標(biāo)與指標(biāo)權(quán)重的模糊性,利用直覺(jué)模糊集對(duì)其進(jìn)行表示,并結(jié)合TOPSIS構(gòu)建邊坡地震穩(wěn)定性評(píng)價(jià)模型;最后利用模型對(duì)16處邊坡地震穩(wěn)定性進(jìn)行評(píng)價(jià),結(jié)果與實(shí)際相符。研究結(jié)果表明:基于直覺(jué)模糊集TOPSIS法的巖土邊坡地震穩(wěn)定性評(píng)價(jià)模型可用來(lái)處理指標(biāo)權(quán)重和定性指標(biāo)的模糊性,與突變級(jí)數(shù)法、屬性數(shù)學(xué)、灰色聚類法、綜合指標(biāo)法、模糊因素法等方法相比,用其得到的評(píng)價(jià)結(jié)果更準(zhǔn)確。
[Abstract]:In order to evaluate the seismic stability of rock and soil slope accurately, a slope seismic stability evaluation model based on intuitionistic fuzzy set approximation ideal solution ranking method is established. Firstly, considering the quantitative and qualitative indexes, the characteristics of rock and soil mass and the characteristics of neotectonic movement are selected. Six factors, such as slope height, slope angle, annual precipitation and site seismic intensity, are the evaluation indexes of slope seismic stability, and then, aiming at the fuzziness of qualitative indexes and index weights, the intuitionistic fuzzy sets are used to express them. Finally, the seismic stability of 16 slopes is evaluated by using the model. The results show that the seismic stability evaluation model based on intuitionistic fuzzy set TOPSIS method can be used to deal with the fuzziness of index weight and qualitative index, and it can be used to deal with the sudden change series method, attribute mathematics, grey clustering method. Compared with the synthetic index method and fuzzy factor method, the evaluation results obtained by the method are more accurate.
