【摘要】：為了更好地預(yù)測地震滑坡的危險(xiǎn)性,根據(jù)信息融合,提出一種基于證據(jù)理論和熵權(quán)灰色關(guān)聯(lián)法的地震滑坡危險(xiǎn)性預(yù)測模型,即以證據(jù)理論為模型基礎(chǔ),以滑坡危險(xiǎn)等級為識別框架,根據(jù)地震滑坡發(fā)生所需要的條件,選取巖石風(fēng)化系數(shù)、地震烈度、斷裂帶密度、河網(wǎng)密度、相對高度、山體坡度這6項(xiàng)指標(biāo)作為證據(jù)體,并采用熵權(quán)灰色關(guān)聯(lián)法確定各證據(jù)體的確定信度。通過分析并且采用國內(nèi)若干組滑坡實(shí)例對模型進(jìn)行驗(yàn)證。研究結(jié)果表明:該方法具有較高的預(yù)測精度,可靠合理,能滿足抗震防災(zāi)規(guī)劃要求。
[Abstract]:In order to better predict the risk of earthquake landslide, according to the fusion of information, a prediction model of seismic landslide risk based on evidence theory and entropy weight grey correlation method is proposed, which is based on evidence theory. Taking the dangerous grade of landslide as the identification frame, according to the conditions needed for the occurrence of earthquake landslide, six indexes of rock weathering coefficient, seismic intensity, density of fault zone, density of river network, relative height and slope of mountain body are selected as evidence body. And the entropy weight grey correlation method is used to determine the reliability of each body of evidence. The model is verified by analyzing and using several sets of landslide examples in China. The results show that the method has high prediction accuracy, reliability and rationality, and can meet the requirements of seismic disaster prevention planning.
