优势结构面控制的岩质边坡强震破坏机制研究OA北大核心CSCDCSTPCD
FAILURE MECHANISM OF PREFERRED STRUCTURE PLANE CONTROLLED LITHOLOGIC SLOPE DURING INTENSIVE EARTHQUAKE
据统计,由地震所造成的损失中,地震所诱发的滑坡和崩塌造成的损失约占40％.对于地震作用下斜坡变形破坏的类型与机制,前人已有大量的研究和归纳,然而对此问题的数值模拟研究则少有涉及.四川省什邡市北部山区在5·12汶川地震中烈度达到11度,遥感解译出的地震诱发崩滑体地质灾害点达161处,其破坏机制主要有顺层-切层滑坡和滑移式崩塌2种形式.本文针对这一地区2种典型滑坡地质灾害,利用赤平投影图分析方法确定边坡的控稳优势结构面组合,在此基础上用离散元数值模拟…查看全部>>
According to statistics, the damage caused by earthquake-induced landslides and collapses can account for about 40% of all that causes by earthquake. As for the mechanisms and modes of slope deformation and failure under seismic force, a lot of previous theories and achievements have been reached. But, numerical simulation research is limited. The seismic intensity of the northern mountainous area of Shifang City, Sichuan province reached 11 degrees during t…查看全部>>
