由於山前帶高陡巖層出露或巨厚礫石層的覆蓋、地表起伏大等復雜的地表條件、逆沖和逆掩推覆等復雜地下地質構造發育、速度橫向變化劇烈等原因，造成了山前帶地震勘探資料採集存在次生干擾嚴重和信噪比低等一系列問題。 -
On the basis of the concept and analysis method of slope geological structure, four typical slope geological structures are selected by some investigations on more than one hundred high rock slopes in the motorway project. these structures are thick sandstone stratum, stratum including weak coal, stratum made of red or brown plastic clay and soft rock mass and stratum made of remnants rock mass. the practical slope geological structures are compact basis of geological mechanical model for the analysis of relaxation zone in high rock slope projects
在介紹了坡體結構概念並提出建立坡體結構方法的基礎上，根據對京珠高速公路粵境北段路塹高邊坡工程中百余處巖石高邊坡的調查總結，選擇了其中較為具有代表意義的厚層砂巖、煤系地層、紅土地層及殘坡積層路塹高邊坡共4類巖石高邊坡作為研究對象，為對巖石高邊坡開挖鬆弛區的分析打下了堅實的實際地質力學模型基礎。 -
