【摘要】 本文依托大连滨海国家地质公园,通过对波浪侵蚀下基岩海岸带斜坡的初步工程地质调查,结合工程动力地质学与岩土力学原理,分析了基岩海岸带斜坡地质灾害类型与诱发因素及其对海岸基础结构的影响;在此基础上,考虑基岩海岸斜坡地质结构特点及边坡宏观破坏型式,概化出海岸带斜坡变形破坏的5种类型,即顺层滑动破坏、倾倒破坏、楔体破坏、五面体破坏、切割坡脚型破坏,并推荐了相应的稳定性评价方法;进一步以图片形式展示了海浪侵蚀形成的各类独特海蚀地貌景观,如海蚀崖、海蚀石林、海蚀龛、海蚀穴、海蚀洞、海蚀拱桥、海蚀平台、海蚀柱、海蚀残丘等,在分析其成因机制的基础上,提出了有针对性的地质遗迹无损加固技术和保护措施,并建议了今后海岸带斜坡与地质遗迹变形破坏及稳定性评价研究的新思路。
【Abstract】 Based on the preliminary engineering geology survey of coastal rock slope in Dalian National Geological Park,the inducing factors and types of geological hazard of coastal rock slope are analyzed in combination with the principles of engineering dynamic geology and geotechnical mechanics.The effect of geological hazard on the coastal infrastructure is also analyzed.The modes of coastal slope deformation and failure are summarized according to slope macro failure forms and geological structure characteristics:bedding slip failure,toppling failure,wedge failure, pentahedron failure,cutting slope toe failure.The stability evaluation method for each type is proposed in this work.The wave erosion landscapes are shown in pictures such as sea cliff,sea erosion stone forest,sea notch,sea cave,sea arch bridge,sea platform,sea stack,and sea monadnock.Nondestructive reinforcement technique and protection measures for these landscapes are presented based on the analysis of their formation meclianism.
