摘要：黃土滑坡是我國西北地區(qū)最為嚴重的地質(zhì)災(zāi)害之一，它不僅給人民的生命財產(chǎn)帶來危害，同時還制約著社會經(jīng)濟的發(fā)展.為查明西安市灞橋區(qū)王家坡滑坡體的特征，應(yīng)用微動探測法，通過野外數(shù)據(jù)采集、室內(nèi)資料處理-空間自相關(guān)法（SPAC法）及成果解譯查明了該滑坡體的地層分布、滑面位置及構(gòu)造發(fā)育特征，并結(jié)合鉆孔資料證明了微動探測法在滑坡勘查中結(jié)果準(zhǔn)確可靠且費用低.通過工程實例表明：微動探測技術(shù)能夠為防災(zāi)減災(zāi)提供一定的技術(shù)支撐，是一種很有前景的工程物探方法.

Abstract： Loess landslide is one of the most severe geological disasters in northwest China. It not only does great harm to people's life and property， but also restricts of social and economic development. In order to find out the geological characteristics of Wangjiapo landslide in Baqiao District of Xi'an City， this study used micromotion detection method. The ground distribution， slide surface location and structural development characteristics of the landslide were ascertained by means of field data acquisition， indoor data processing and spatial autocorrelation（SP AC） method and result interpretation. Additionally， by combining drilling data， it is demonstrated that the micromotion detection method yields accurate and reliable results at a low cost for landslide exploration. The engineering example shows that micromotion detection technology can provide certain technical support for disaster prevention and reduction， which is a very promising engineering geophysical exploration method.
