摘要
2006年1月27日,贵州省威宁县猴场镇幺岩脚发生崩塌灾害,上午10点开始有石块坠落,持续到下午5点左右,崩塌体规模0.5×104m3左右(残留2个危岩体),幺岩脚边坡岩层近水平,上部为灰岩,下部为泥页岩。因此,本区可以作为分析这类近水平上硬下软边坡失稳破坏机制的理论研究基地,通过分析该区域的变形破坏特征,对这类边坡的研究和治理具有一定的指导意义。
A collapse disaster occurred in YaoYan Jiao slope, HOUCHANG, WEINing country. By 10 a. m. start fall- ing rocks, continued until around 5 μm. , Collapse body size of 0.5×10^4m^2 around（ Residue 2 dangerous rock）, rock formations of YaoYan Jiao Slope rock nearly horizontal, The upper is limestone, The lower is the clay shale. Therefore, the area can be used as a theoretical research base to study such nearly level hard under the soft type slope instability and failure mechanisms. Through the analysis of the regional characteristics of deformation and failure of this kind of slope, re- search and management has certain direct sense.
