back slipping meaning in English

向后滑动

According to composition and structure feature of jinjiang landslide analysis , the author considers it was a enormous landslide with the characters about multi - period ( total four slides ) and overlaying , its mechanism of deformation failure attributed to a representative sliding - bending mode in the consequent slope , the stability calculation indicates that no matter what the whole landslide would not slide , while , as earthquake intensity reaching or exceeding vi , the first - period landslide which lies to the south of huangjiagou in the front slip mass and the fourth - period landslide which lies to the north of caojialiangzi in the back slip mass will slide
由金江滑坡的组成及结构特征分析可知，边坡为一多期次(四次滑动)兼具超覆特征的巨型滑坡，其变形破坏机制属顺层边坡中比较典型的滑移?弯曲型。稳定性计算表明，滑坡整体稳定性较好，仅在遭遇度及其以上地震作用的情况下，堆积体前部靠黄家沟以南的第一期滑坡及靠后部北侧曹家梁子的第四期滑坡堆积体才会失稳；因素敏感性分析表明，滑坡稳定性对地震(尤以强震)最为敏感。
