壓痕，因相紙被折曲或被力壓而產生的條紋-
The mesoproterozoic mafic dyke swarms are extensively distributed in the central north china craton, which are not deformed and metamorphic, emplacing the pre - existed fractures, so the dyke swarms become the conspicuous marks to reconstruct the mesoproterozoic tectonic stress field of the central ncc. the mafic dykes in the northern block are transtensional while the dykes in the central and southern blocks are extensional. the mesoproterozoic tectonic stress field could be simulated on the analysis of the distribution and mechanical origin of the mesoproterozoic mafic dyke swarms in the central ncc. the simulation result shows that the mafic dyke swarms were formed in the extensional tectonic setting in the ncc in the mesoproterozoic time, which are related to the extension of the mesoproterozoic yanliao - zhongtiao aulacogens cross the central ncc
克拉通北部地塊的鎂鐵質巖墻群為張剪性，而中部和南部地塊為張性。根據華北克拉通中部中元古代鎂鐵質巖墻群的分佈和成因機制分析，來恢復模擬中元古代的構造應力場。數值模擬結果表明鎂鐵質巖墻群在中元古代形成於伸展的大地構造背景，與橫穿華北克拉通中部的燕遼-中條拗拉槽系的伸展作用有一定的聯系。 -
At first it analyzes the bedding rock slope ' s bedded rock and its incontinuity face, and studies the stress, strain, stability ' s condition of the bedding rock slope, fully considering the cohesive force of rock layer and incontinuity face. geologic mechanics models of two types of bedding rock slope are set up, the instability coefficient of bedding rock slope under different mechanical parameters is computed, and the conclusion that the stability of bedding rock slope is relation to rock layerer, cohesive force of incontinuity face, inner friction angle and rock layer obliquity has been gotten. based on the above discussion, the thesis comes down the influence of rock layer and the incontinuity face on the bedding rock slope to incontinuity face ' s influence factors, and discusses other factors that influence the bedding rock slope ' s stability, so gains the evaluating and forecasting index marks
本文首先對順層邊坡的層狀巖體及其中的層理面和不連續面進行了分析，對其應力應變進行了研究，得出了順層邊坡的穩定性不僅與巖體中巖石的強度有關，還與巖體中層理面及不連續面的內聚力、內摩擦角及其傾角有關；論文建立了層理面和節理面的地質力學模型，討論了其力學參數變化對邊坡穩定性的影響，並在此基礎上將層理面和節理面歸納為順層邊坡穩定性的結構面影響因素，同時討論了影響順層邊坡穩定性的其他因素，從而得出順層邊坡穩定性的評價預測指標。 -
On the basis of these data and pictures, the sedimentary characteristics of quaternary system stratum and the location and activity of occult faults and the specific marks of realm seismicity and the characteristics of deep geophysical field and the tectonic stress field and the ground temperature field and the seismogeological disaster characteristics and the forcast and assessment on earthquake stonebrash liquefaction of the yellow river delta had been analysed and worked over synthetically and closely by the author too. meanwhile, the seismicity variance between the yellow river delta and bohai seismic zone had also been analysed
經過對這些資料的綜合系統分析，對黃河三角洲地區第四系地層沉積特徵、隱伏斷裂的位置及活動性、區域地震活動特性、深部地球物理場、構造應力場、地溫場特徵，地震地質災害特徵和地震砂土液化預測評價等做了較為深入的研究，對比分析了渤海強震區與黃河三角洲地震地質特徵的差異性，取得了具有重要意義的成果。
