摘    要:以严重影响吉林-珲春高速公路建设的延吉盆地强膨胀软岩边坡为例,证实了在延吉盆地发育有大量的强膨胀软岩,并通过现场调研、取样、大量的室内试验和理论分析相结合的综合手段揭示出延吉盆地强膨胀软岩边坡的变形机理,即“蠕滑拉裂,梯级牵引,大雨大动,无雨微动”,同时针对强膨胀软岩边坡复杂的变形力学机制,采用关键技术将复杂性变形力学机制转化为单一型变形力学机制,并提出了具体防治措施.

关 键 词:延吉盆地  强膨胀软岩边坡  变形机理  防治措施

Abstract:Took strongly expansive slopes of Yanji Basin which badly affected the construction of Jilin Huichun speedway as an example, confirmed strongly expansive soft rocks develop abroad in Yanji Basin, and presented their deformation mechanism by the means of synthesizing practical investigation, sampling, lots of laboratory tests and theory analysis. This mechanism was characterized as creep stretching, stepped retrogressing, and moving great in the case of heavy rains while tinily without rains. Meanwhile, for the complex mechanism of deformation of strong expansion soft rock slope, the complex mechanical deformation mechanism was translated into the single one and prevention measures was proposed.
Keywords:Yanji Basin  strongly expansive softrock slope  deformation mechanism  prevention measures
