【摘要】 因处于复杂而特殊的地质环境,国道212线新改线大(岸庙)姚(渡)中的福津河段滑坡非常发育,表现为集中性、规模大、两岸不对称性和严重性等显著特征。分析和研究表明,与所有滑坡一样,本段滑坡是各种地质环境因素(地形地貌、构造运动和新构造运动、地质构造、地层岩性等)综合作用的结果,但上述显著的分布和发育特征主要受控于新构造运动、地震和千枚岩层产状及其与山坡坡度的组合关系。研究结果为本段新建和改建公路的规划和设计提供指导性参考意见。更多还原

【Abstract】 <Abstrcat>The highway along the Fujin river, a division of the Bailong river, is a planning road of the national highway G212 to be reconstructed. In this section, there are lots of landslides with such significant characteristics, such as concentration, large scale, non-uniform distribution on both banks, because of its special and complicated geological environment. It is demonstrated that these landslides specially are controlled by neotectonic movements earthquake, lithology the characteristics and attitude of phyllite mass with thin layered structure. These understandings can provide guides for planning and designing the new G212.更多还原
