群體沉降 的英文怎麼說
中文拼音 [qúntǐchénjiàng]
群體沉降
英文
group settling-
Different situations, single - pile raft, four - pile raft and nine - pile raft, are calculated with cpri. with the computing results, the variation of the raft settlement, pile counterforce, soil counterforce and pore pressure at different time are analyzed, which agree with the general rule and show the contribution of soil consolidation on the interaction
本文利用cpri分別對單樁承臺、四樁承臺和九樁承臺的工作性狀進行了計算分析，模擬樁基的沉降發展過程和不同時刻土體中的孔壓、樁身荷載、承臺底面土體反力的變化，分析了群樁承臺的荷載在各樁頂的分佈。From the research results, we can see that the initial reason, which leads to the degradation of xuanwu lake ecosystem, is pollution. pollution makes the water and sediments hypertrphiation, increases the opacity of water, and decreases the oxygen in water, so the wetland higher plant communities decrease or disappear. the wetland ecosystem loses the balance, while the biodiversity also decreases
研究結果表明，引起玄武湖濕地生態系統功能退化的初始原因是嚴重的環境污染問題，污染加劇了水體及沉積物中的營養鹽含量，增加了水體的渾濁度，降低了水體中的氧含量，從而導致濕地高等植物群落減少乃至消失，盡而引起濕地生物多樣性下降、生態系統失去平衡。Such a model of egg production would be benefit this species to survive in this waters area and become a dominant species. for subitaneous eggs, in winter - spring with long hatching time, the females lay in nighttime in upper water layer. the distance for eggs sinking to the sea - bottom is also long
對于滯育卵來說，雌體日間在海區下層水體產卵，可使得滯育卵快速沉至海底，縮短滯育卵在水體中的滯留時間，降低在水層中被攝食的風險，同樣也有利於個體的存活和種群的延續。( 4 ) in the interaction analysis of pile ? at foundation, the shear ? eformationed method which only deal with a single pile in homogeneous body previously has been developed so that the interaction analysis of piles with layer soil has been completed successfully. based on the flexible coefficient of the single pile, that coefficient of pile ? ile, pile ? oil or soil ? ile has been deduced, then rigid matrix of system of piles and layer soil can be gained
（ 4 ）在樁土共同作用分析中，本文發展了計算單樁沉降的剪切位移法，在得到單樁位移柔度系數的基礎上，進一步得到了樁?樁相互作用位移柔度系數和樁?土相互作用位移柔度系數，從而得到了樁?土體系的剛度矩陣，使之可用於進行層狀地基中群樁與土的共同作用分析。分享友人
