骊山滑坡Ⅱ区变形稳定性分析

Stability Analysis on District Ⅱ of Lishan Landslide

骊山滑坡位于西安市临潼区骊山北坡,按稳定程度将其分为六个区。Ⅰ区位于华清池正上方、三元洞上下,经详勘查明是潜在的黄土及浅层基岩沿破碎基岩中缓倾角断层滑坡,已于1997年至2002年进行了工程治理,目前该区基本稳定。Ⅱ区为晚照亭下方的隆起部分,以破碎基岩错落为主,上覆第四纪崩坡积物,多年来一直在发生变形。本文结合Ⅱ区地质地貌及地层岩性,对多年的监测资料进行综合分析,得出该区目前的稳定性评价,为进一步做好防灾减灾工作提供依据。

Lishan landslide is located in the northern slope of Lishan in Lintong District of Xi＇an. District I of Lishan landslide is located at the top of the Huaqing Pool and around Sanyuan Cave, which is the slide of the yellow and shallow bedrock along the broken rock in the low-angle faults. This area is currently stable after the project management from 1997 to 2002. District II of Lishan landslide is located at the bottom of Wanzhao Pavilion, which is mainly scattered with broken rocks and covered by Quaternary product-slope collapse. This area is not stable until now. In this paper, the data of deformation monitoring is systemically analyzed according to geological features of District II, and the evaluation of the current stability is obtained. It provides a basis for disaster prevention and reduction.
