The results indicate that : 1. the main physical and chemical characteristics vary regularly : with rising of the altitude, there is a transition from silt > sand > clay to sand > silt > clay in the mechanical composition ; the argic horizon emerges below the altitude of 1600 meters ; the content of organic matter is enrichment, the content of organic carbon of epipedon is higher than 20 g / kg, while the content of organic carbon increases with increasing of altitude, and in the altitude of 3500 - 3700meters, the soils under the meadow have the maximum content organic carbon ; the soils appear acid - slightly acid reaction, the ph decreases appreciably and acid strengthen with increasing of altitude ; the soils higher than the altitude of 2500 meters are base unsaturated, indicating the soil leaching is strong, the ph and bs are distinct plus correlated ; the contents of sio2, al2o3, and fe2o3 of the soil body and clay are all relatively stabilization ; in the soil body, the content of sio2 is much high and cao is very little, the total contents of sio2, a12o3 and fe2o3 occupy 92 % of the mineral parts, the sequence of mineral elements is : sio2 > al2o3 > fe2o3 > k2o > mgo > cao > tio2 > mno
研究結果表明： 1太白山南坡土壤的主要理化性質隨海拔高度的上升呈有規律的變化：隨海拔高度上升，機械組成由粉粒砂粒粘粒逐漸過渡到砂粒粉粒粘粒，海拔1600m以下出現粘化層；土壤有機質豐富，表層有機碳含量一般在20g kg以上，有機碳含量隨海拔高度升高而相應增加，海拔3500 3700m的灌叢草甸植被下有機碳含量最高；土壤呈酸性或微酸性，並隨海拔上升， ph值略微降低，酸性增強，海拔2700m以上的土壤多呈鹽基不飽和狀態，表明土壤淋溶作用較強， ph值和鹽基飽和度呈極顯著正相關；土體與粘粒中的sio _ 2 、 al _ 2o _ 3 、 fe _ 2o _ 3含量相對比較穩定，土體中sio _ 2含量較高， cao含量較少， sio _ 2 、 al _ 2o _ 3和fe _ 2o _ 3含量之和約占土壤礦質部分的92 ，礦質元素含量的順序依次為： sio _ 2 al _ 2o _ 3 fe _ 2o _ 3 k _ 2o mgo cao tio _ 2 mno 。This thesis emphasizes to proceed the study on the mechanism of formation of the reservoirs of lower palaeozoic burial hills in the regions of zhuangxi and chengdao from the angle of geochemistry. the research of petrology reveal rock types of the regions mainly include carbonate rock, claystone, siltstone, breccia and a few of evaporite rock
巖石學研究表明，樁西、埕島地區下古生界古潛山儲層的巖石類型有碳酸鹽巖、粘土巖、碎屑巖、以及少量蒸發巖，其中碳酸鹽巖是該區下古生界古潛山儲層最主要的巖石類型，為一種穩定地臺型海相沉積環境的產物。Based on the creep experimental curve, the creep deformation law of silty soft clay of the first marine layer and its constitutive relationship among stress - strain - time is studied in this paper
本文在蠕變試驗曲線的基礎上，研究了天津市第一海相層淤泥質粉質粘土的蠕變變形規律，得出應力、應變、時間三者之間的本構關系。2. the relationships between the nutrients exchange rates and the potential environmental controls it was observed that the exchange rates of sio3 - si were correlated with the temperature, do, ph, salinity of the seawater, the water and clay contents of the sediments and the concentrations of sio3 - si in the overlying water and pore water of the sediments
2 、影響營養鹽在東海沉積物一海水界面交換速率的主要因素sio _ 3 - si在東海沉積物?海水界面交換速率與水體溫度、 do濃度、 ph值、鹽度、沉積物的含水率、粘土礦物含量、間隙水中sio _ 3 - si濃度、上覆水中sio _ 3 - si濃度均存在很好的相關性。Abstract : in this paper the visco - elasticity constitution relationship of cyclic degradation describing offshore soft clay behaviors is studied. a method for quantitatively analyzing the stability of offshore soft soil sites under wave loading is developed by combining the relationship with water - mud multi - layer interface model. since the variation of nonlinear visco - elasticity parameters due to cyclic degradation of soft clay can be considered, the analytic results can reflect the changing process of soft clay under wave loading
文摘:本文研究了海洋軟土的循環弱化粘彈性本構關系，進而把它與波浪、水、土多層計算模型相結合，提出一種定量分析波浪作用下海洋軟土場地穩定性的方法.由於它考慮了軟土的循環弱化而導致的非線性粘彈性參數的變化，使分析結果能比較真實地反映波浪作用下海洋軟土層的變化過程分享友人
