摘要：赫章縣七家灣氣象站滑坡屬于中型推移式滑坡，橫寬為200 m，縱長(zhǎng)為90 m，主滑向?yàn)?36°，滑坡平均厚度為10 m，體積為180 000 m3。本文結(jié)合滑坡區(qū)自然環(huán)境特征，分析滑坡發(fā)育特征和變形特征，明確滑坡失穩(wěn)機(jī)制，然后開展滑坡穩(wěn)定性評(píng)價(jià)，提出滑坡防治方案，最終消除地質(zhì)災(zāi)害風(fēng)險(xiǎn)。

Abstract： The Qijiawan Meteorological Station landslide in Hezhang County belongs to a medium-sized translational landslide， with a horizontal width of 200 m， a vertical length of 90 m， a main sliding direction of 336°， an average thickness of 10 m， and a volume of 180 000 m3. Based on the natural environmental characteristics of the landslide area， this paper analyzes the development and deformation characteristics of landslides， clarifies the mechanism of landslide instability， and then conducts landslide stability evaluation， and proposes landslide prevention and control plans， thus ultimately eliminating geological disaster risks.

Keywords： landslide; instability mechanism; developmental characteristics; deformation characteristics; prevention and control; meteorological station; Hezhang County
