21282.寶雞市陳倉(cāng)區(qū)滑坡災(zāi)害危險(xiǎn)性評(píng)價(jià)研究

1、論文題目：寶雞市陳倉(cāng)區(qū)滑坡災(zāi)害危險(xiǎn)性評(píng)價(jià)研究專(zhuān)業(yè)：地質(zhì)工程碩士生：陳偉(簽名)指導(dǎo)教師：侯恩科(簽名)摘要近年來(lái)，因滑坡災(zāi)害造成的人員傷亡及財(cái)產(chǎn)損失事件越來(lái)越頻繁，也引起了人們?cè)絹?lái)越多的關(guān)注。本文在對(duì)寶雞市陳倉(cāng)區(qū)滑坡災(zāi)害的發(fā)育條件、地質(zhì)環(huán)境背景、分布特征及其主要影響因素研究的基礎(chǔ)上，分區(qū)域（l:5萬(wàn)調(diào)查資料）、重點(diǎn)地段（l:1萬(wàn)調(diào)查資料）兩個(gè)方面進(jìn)行了陳倉(cāng)區(qū)滑坡災(zāi)害危險(xiǎn)性評(píng)價(jià)研究，取得了下列主要進(jìn)展和成果：（1）以寶雞市陳倉(cāng)區(qū)滑坡災(zāi)害調(diào)

2、查資料為基礎(chǔ)，分析了研究區(qū)內(nèi)滑坡災(zāi)害的類(lèi)型及分布特征，研究了地形地貌、地層巖性、地質(zhì)構(gòu)造、降雨、水文地質(zhì)條件、人類(lèi)工程活動(dòng)、地震等影響滑坡災(zāi)害形成的主要因素；（2）選取地貌類(lèi)型、工程地質(zhì)巖組、地質(zhì)構(gòu)造、坡度、坡向、高程、土地利用類(lèi)型、地震動(dòng)峰值加速度、降雨和人類(lèi)工程活動(dòng)等因素作為滑坡災(zāi)害發(fā)育的主要影響指標(biāo)，初步建立了寶雞市陳倉(cāng)區(qū)滑坡災(zāi)害危險(xiǎn)性評(píng)價(jià)的指標(biāo)體系；（3）以GIS為工具，利用信息量法將寶雞市陳倉(cāng)區(qū)滑坡災(zāi)害危險(xiǎn)性劃分為極高危險(xiǎn)區(qū)、

3、高危險(xiǎn)區(qū)、中等危險(xiǎn)區(qū)、低危險(xiǎn)區(qū)和極低危險(xiǎn)區(qū)，完成了寶雞市陳倉(cāng)區(qū)區(qū)域滑坡災(zāi)害危險(xiǎn)性評(píng)價(jià)；（4）運(yùn)用因子權(quán)重疊加模型評(píng)價(jià)方法，采用與區(qū)域滑坡災(zāi)害危險(xiǎn)性評(píng)價(jià)相同的評(píng)價(jià)指標(biāo)，并針對(duì)不同重點(diǎn)區(qū)段進(jìn)行適當(dāng)調(diào)整，在采用層次分析法確定各評(píng)價(jià)指標(biāo)的權(quán)重后，對(duì)寶雞市陳倉(cāng)區(qū)寶中線黃土分布區(qū)段和隴海線基巖分布區(qū)段兩個(gè)重點(diǎn)區(qū)段的滑坡災(zāi)害進(jìn)行了危險(xiǎn)性評(píng)價(jià)。關(guān)鍵詞：滑坡災(zāi)害；危險(xiǎn)性評(píng)價(jià)；信息量模型；層次分析法；陳倉(cāng)區(qū)研究類(lèi)型：應(yīng)用研究Subject:Studyont
