Kongxi buried hill shows following features in the seismic profiles : the structures are asymmetric. there is flexural syncline on the east side and a monocline on the west side. asymmetric repetition of stratigraphic units is present in the drill wells and the dips of beds and faults are gentle. the permo - carboniferous system of both sides almost lie in the same slope and the events of cambrian or upper proterozoic are continuous from east to west. the phenomenas suggest that kongxi buried hill could be a thrust belt been traced which consists of reverse faults. the imbricate faults mainly effect pre - jurassic strata. there are obvious angular unconformity between jurassic - cretaceous system and paleozoic involved deformation of thrust. the thrust front in some place has cut off the beds of jurassic - cretaceous system. the structural style of the thrust structure changes along the strike of the kongxi buried hill
地震和鉆井資料揭露的孔西構造帶前第三系潛山的地質特徵可以歸納為：構造帶總體上不對稱構造帶內部有地層重復現象石炭二疊系地層的位置明顯高於兩側的同一地層的高度。用由34條向東傾斜的逆沖斷層組成的疊瓦扇構造模式能夠比較合理地解釋上述地質特徵。該帶向東傾斜的逆沖疊瓦狀斷層組主要影響前侏羅系地層，侏羅白堊系與捲入逆沖構造變形的古生界地層之間有明顯的角度不整合。 -
The main work this paper do are these like below : ( 1 ) this paper reviewed and summarized the development and actuality of bank in china, induced the variety of bank ' s disease and the measure of judge etc. ( 2 ) introduced and studied fast lagrangian analysis of continua. flac3d is a three - dimensional explicit finite - difference program. uing this program, obtained the three - dimensional settlements of huxi bank and analyzed the tention area and the cut - off area. the result shows that there are a lot of andscape orientation cracks and portrait cracks in the bank. these cracks bring some disadvantage influence to slope stabilization and seepage of bank
主要內容如下： （ 1 ）回顧總結我國堤防發展的基本狀況及運行現狀，對堤防病害的種類及評判方法進行歸納。 （ 2 ）對三維快速拉格郎日有限差分法進行了深入研究，並運用此理論對地下采動的結構和過程進行了數值模擬，對湖西大堤姚橋礦段由於地下採煤而引起的不均勻沉降進行了計算，得出堤體及其周圍地基的三維位移場，分析了由於不均勻沉降而產生的拉應力區和剪切破壞區域。
