研究目的:针对工程隐患较大且整治困难的长大顺层滑坡,深入分析其分段滑动破坏机理,并提出具体施工防治措施.研究结论:(1)该长大顺层滑坡的分段渐进性破坏是受应力条件,炭质泥岩软化特征的综合影响,其中炭质泥岩的易滑特征起主导作用,工程建设中应多加重视;(2)该类滑坡的整治措施,多以抗滑桩为主,但由于目前滑体变形错动较大,且施工工期紧张,实际治理以锚索框架+钢管桩的综合治理为主要方案,且效果较好.%Research purposes: Due to the might - be serious project risk and the difficult remediation of long and large bedding plane landslide, this paper analyzes the sublevel sliding destroy mechanism and proposes protection methods for concrete construction.Research conclusions: ( 1 ) The piecewise progressive destroy results from the combined effect of force condition and the soften characteristics of charcoal mudstone, with slippery characteristics playing a major impact; thus the charcoal mudstone should be paid special attention to in construction.(2) Anti - slide pile is considered as a major remediation towards such landslide, however, because of the landslide's deformation displacement and the limited time, it is better to use the AF&SPP( Anchor Frame and Steel Pipe Piles) methods on landslide management.
