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。The basement of the basin is consist of precambrian crystal basement and paleozoic folding basement, while the cover has undergone the evolution of intra - continental rife in permian, down warped basin in triassic - cretaceous period and inter - mountains basin in tertiary. the main sediments are huge - thick volcanic rock, shallow intrusive rock and tuff in early permian, dark mudstone, marl and muddy dolostone in lucaogou formation in middle permian, huge thick volcanic rock, intruder in tiaohu formation in middle permian, miscellaneous sandy gravel, sandstone and gray mudstone in triassic ( the red is under the gray, and huge - thick dark gray, gray sandy gravel, sandstone, mudstone with coal layer in jurassic
盆地基底由前寒武紀結晶基底和古生代褶皺基底組成，盆地蓋層則經歷了二疊紀的裂谷盆地、三疊紀?白堊紀的坳陷盆地和第三紀后的山間盆地的演化過程。盆地主要沉積了下二疊統巨厚火山巖、淺成侵入巖和凝灰巖；中二疊統蘆草溝組的暗色泥巖、泥灰巖、白雲質巖石以及條湖組的巨厚層火山巖、侵入巖；三疊系雜色砂礫巖、砂巖及灰色泥巖（下紅上灰） ；以及侏羅紀厚層深灰、灰色砂礫巖、砂巖、泥巖夾煤層。The palaeogeographic research indicate that the palaeogeographic outline of the study area recorded the evolution from a sedimentary basin in which the shallow - water carbonate platform sediments and deep - water terrigenous clastic submarine fan developed from southeast to northwest and northeast during the late triassic through a submarine sheet - like model composed of deep - water sandy turbidite and fine - grained turbidite during the early jurassic to a terrigenous clastic barrier coast during the middle and late jurassic and finally to the coal - bearing delta sediments during the late cretaceous
古地理分析表明，研究區晚三疊世古地理輪廓是一個從東南向西北和東北方向由淺水碳酸鹽臺地及深水陸層海底扇沉積共同發育的沉積盆地；早中侏羅世，演變成為一個由深水砂質濁積巖和細屑濁積巖組成的水下席狀體沉積；進入中晚侏羅世，其古地理表現為一個陸屑淺海有障壁海岸；到了晚白堊世，研究區表現為以含煤沉積為特徵的三角洲相沉積。On the basis of comprehensive analyses on hydrocarbon accumulation conditions in the four representative foreland basins, kuqa basin, southern junggar basin, western sichuan basin and northern margin of qaidam basin, some conclusions are made as follows ; the foreland basins in central and western regions of china are characterized by multi - set source rocks dominated by coal measure ; heterogeneous reservoirs ; multiple and sealing cap nick ; anticline traps ; unblocked transport system composed of fault, unconformity and highly permeable sand body ; anti poor conservative conditions. etc
在綜合分析和對比庫車、準南、柴北緣和川西等具有代表性的前陸盆地的油氣成藏條件的基礎上指出，中西部前陸盆地具有以煤系為主的多套源巖，發育非均質儲集層，多套多封閉性的蓋層，以背料為主要圈閉；斷裂、不整合和高滲透砂體組成良好輸導體系，保存條件較差等特點。分享友人
