英文
sandy loess-
The elementary idea of the reference units method can be described as follows : firstly, by the setting of double series of reference units, we can control the highest and lowest land quality class of each village or town ; secondly, the class of the arable land will be get through the contrast between the arable land with the reference unit which has been selected in the same area, the difference in quality is the key factor to classify the land. the results show, 87. 6 % of the lands from i to iii distribute on alluvial and lacustrine plains, where the associated soils are mainly grey fulvo - aquic and calcareous concretions black ones. and 61. 4 % of them from iv to vi distribute on slightly rolling parts with mainly yellow - cinnamon soil developed from the diluvial and slope deposits
分等結果表明:臥龍區等的耕地中,有87 . 6分佈在沖積、湖積平原區,主要土壤類型是在河流沖積物上發育形成的灰潮土、在湖相沉積物上發育形成的砂姜黑土;等耕地中,有61 . 4分佈在壟崗區,主要土壤類型是洪坡積物上發育形成的黃褐土:而、等耕地集中分佈在丘陵區,主要土壤類型是殘坡積物上發育形成的粗骨性黃褐土,等別結果分佈總體上體現了不同地貌類型、土壤條件下耕地質量的差異。Since 1950s, changjiang water resources commission as well as other scientific research units have carried out engineering geological reconnaissance for large - scale cross structures and the whole route, meantime, researched special subjects, such as special soils ( expansive soil, loess ), the canal section in coal mining area, regional structure stability, sandy soil liquefaction etc
自20世紀50年代迄今,長江水利委員會及其它科研設計單位對中線工程全線及大型交叉建築物進行了工程地質勘察,同時對特殊類土(膨脹土、黃土) 、渠線過煤礦區、區域構造穩定性、砂土液化等專題進行了研究。The forcast and assessment on earthquake stonebrash liquefaction of the yellow river delta had been analysed and worked over synthetically and closely for the first time in the history, eventually, it was proved that the earthquake stonebrash liquefaction was the predominant disaster in the yellow river delta and several regions would bring about earthquake stonebrash liquefaction disaster when the intensity of an earthquake was 6 degree
開展了黃河三角洲第四系沉積特徵方面的研究4首次全面的對黃河三角洲地區地震砂土液化進行區劃和預測評價,提出地震砂土液化是黃河三角洲主要的地震地質災害,當地震烈度為時,部分地區將產生液化的新觀點。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。分享友人
