Study achievement appears as following aspects : ( 1 ) yellow river estuary gate river flow and tide flow mixed area is not keep standing deposition status, on special income water and sediment conditions, boundary conditions and oceanic power conditions, this area may on the scour status ; ( 2 ) observed from estuary sediment deposition distributing process : delta and sea offing area sediment deposition vary trend is similar, each part sediment deposition scale varies as wave shape ; ( 3 ) on estuary gate, affect the sediment deposition factors, primary factors are tide prop, the gate widens gradually, estuary gate have branches, brine induced flocculation. this paper study the estuary gate widen, estuary gate have branches to affect the river channel deposition in quantity ; ( 4 ) based on field measured data, for the first time, deduce the estuary sediment deposition and distributing regress formula which can estimate estuary different areas sediment deposition volume ; ( 5 ) this subject demonstrate the estuary delta coastline dynamic balance conception, build the relationship between the estuary income sediment with deposition land area, draw the following important conclusion : when estuary years - averaged income sediment keeps at 345 million tons, the delta coastline may on the dynamic balance status. ( 6 ) this subject firstly brings up estuary sediment optimized control conception, and has the primary study on the macroscopically optimized control conception method
研究認為: ( 1 )黃河河口口門逕流潮汐區域並非持續保持淤積狀態,在特定的來水來沙、邊界條件和海洋動力條件下,該區域可以處于沖刷狀態; ( 2 )從河口泥沙沉積分配的過程來看:三角洲與濱海區泥沙的沉積變化趨勢是基本一致的,各部位的泥沙沉積比例變化基本呈波動狀態,且三角洲與濱海區泥沙的沉積比例與來沙量密切相關,基本成正比關系; ( 3 )在口門處,影響泥沙沉淤的因素主要集中在潮汐頂托、口門逐漸加寬、河口門分汊、鹽水造成絮凝等,本報告主要對口門加寬,口門西妥理工大學工程碩士專業學位論文分漢對河道淤積的影響進行了定量分析: (一扣根據實測資料首次建立了河贖流路泥沙沉積分配的回歸計算式,據此可以預估計算河口不同區域泥沙的沉淤量; 、 5 )本項研究首次論證了河口三角洲岸線動態平衡的概念,並建立了黃河河口來沙量與造陸面積的相關關系,得出了當河口多年平均來沙量維持在3 . 45億t時其河口三角洲岸線則可能處于動態平衡狀態的重要結論; 『 6 )本項研究首次提出了河口泥沙優化調控的概念,並對其宏觀優化調控模式進行了初步探討。Despite actualities vary with countries and percentage of sheep and cattle are a bit different, considering the trend on a general level, the percentage of grass - eating animal in our country is lower and less than developed country by 35 %. we must regulate the industry structure. the level of grass - eating animal in shandong province is higher than the national average level, although a bit superior, the gap is still large, the development of grass - eating animal still have a long way to go
盡管各國的實際情況不同,牛羊所佔比例也不盡相同,但從總的趨勢來看,我國草食家畜較發達國家低35 %左右,所佔比例偏低,需要調整畜牧業產業結構,山東省草食家畜超過全國平均水平,有一定的優勢,但從草食家畜發展趨勢來看,差距很大,需要大力發展草食家畜。Investigating from the component of the cost, the expenditure of the labor share about 60 % in the total cost. the result also tells us the production of the china ' s oil crops is labor - intensive, and the degree of the mechanization is very low. using the method of econometrical, the technical efficiency ( te ), the resources allocation efficiency ( ae ) and economy efficiency ( ee ) are calculated for each main province from 1993 to 1998
從我國油料作物生產投入的成本結構來看,我國油料作物的生產成本中勞動力的投入占據了較大的比重,平均在60的水平;而就是在較小比例物質費用的投入當中,以種子、肥料、農藥為主的直接費用又佔有85以上的比例,代表機械化程度的間接費用(資本折舊費、農具修理費等)只佔有很小的一部分比例。The paper draws some valuable conclusions : the limited bearing capacity of manual excavation filling pile is much higher than the limited bearing capacity of machine drilled filling pile ; through grouting injection around the pile shaft, the pile bearing capacity can be effectively improved ; proportion of resistance force around the pile side in total load is much larger than that of pressure on the pile tip, and the intensity of resistance force around the pile side is 30 - 50kpa on average
得出一些有價值的結論:人工挖孔灌注樁的極限承載力明顯高於鉆孔灌注樁的極限承載力;地下水位對樁基承載力有顯著影響;利用樁側注漿可有效提高樁的承載力;樁側摩阻力所佔總荷載的比例遠大於樁底壓力,樁側土的摩阻強度平均值為30 50kpa 。Secondly, by using the great fem programme, analyzes the mechanism of bearing and deformation of rigid - soften composite piles foundation. draw a conclusion : exist a specific value, when the number of the rigid pile less than it, increase the number of the rigid pile, effect of reducing the settlement of rigid - soften composite piles foundation is distinct, on the contrary, when the number of the rigid pile more than it, increase the number of the rigid pile, effect of reducing the settlement of rigid - soften composite piles foundation is indistinct. finally, analyze and sum up some important design ' s constitutes of the rigid - soften composite piles foundation
其次,採用有限元計算程序,對剛柔復合樁基進行了三維有限元分析,考察了在不同荷載水平下,不同剛柔性樁比例的情況下,復合地基的平均沉降量、土體的沉降等值線和應力等值線以及剛性樁和柔性樁樁頂荷載比值隨不同基礎荷載水平的變化規律,得出了一些具有實際指導意義的結論:當總樁數不變,長樁比例增加到一定程度時,再增加剛性長樁的數量對地基整體沉降幾乎沒有什麼效果;剛柔樁分佈一定,柔性樁實際承載力小於其極限承載力時,外加荷載的增加,剛性單樁和柔性單樁所承當荷載的比值基本不變。分享友人
