挖玉是指離開河床在河谷階地干灘古河道和山前沖積洪積扇上的礫石層中挖尋和闐玉礫。這些地方的玉也是由流水帶來的。A brief introduction is given to the treatment of the zeya dam foundation, principles of seepage control and design of the concrete face rockfill dam of the zeya reservoir. as for the excavation of the sand - gravel zones, except the toe slab and its 1 / 9 bottom width down stream, the alluvial layers are excavated to the micro - weathered rocks, while the other sections remain unexcavated. regarding to the treatment of the fracture zones, concrete filling is used for the toe slabs and semi - permeable materials are used for other section. according to the construction characteristics, a filter is placed in the down stream embankment foot. to improve the integrity of the dam foundation and anti - seepage capability consolidation grouting and curtain grouting are adopted. as a result safety, economic benefit, convenience in construction and good performace are achieved
簡要論述澤雅水庫面板堆石壩壩基處理和防滲的原則及設計要點.趾板基礎和堆石體各區砂礫石基礎開挖，除趾板與其下游1 / 9底寬范圍以及壩腳挖除沖積層至弱風化（局部微風化）基巖外，其餘部分均予以保留.斷層破碎帶處理，趾板部位採用混凝土塞，其它部位採用半透水料置換，並根據本工程特點在下游壩腳加設了反濾層.為提高壩基的整體性和防滲性能，對趾板進行了固結和帷幕灌漿.達到了安全、經濟、便於施工的目的，運行情況良好，可為面板堆石壩的設計和研究提供參考與借鑒In this part, the first work is pretreatment of a numerical model, including creating calculating grids automatically, improvement of the linear boundary technique and so on. the second work is to estimate the siltation of a basin or channel by liu ' s equation. the third work is to build an edbms ( engineering data base management system ) for the result of mathematical model
其中主要的工作是：其中主要的工作一是數學模型的前處理，計算網格自動生成，線邊界法的優化；二是應用劉家駒公式在長江口深水航道治理工程地理信息系統的支持下實現港池、航槽開挖的實時回淤估算；三是將計算成果形成gis管理和支持下的工程數據庫系統（ engineeringdatabasemanagementsystem ） ，同時嘗試解決時間序列數據如地形沖淤變化，潮位、流速過程的分析、查詢和顯示問題，並實現實時、互動的動態演示及三維可視化。Excavating riverbeds in one channel may not only reduce the velocity area in some areas but also increase the velocity in other areas by increasing flow rate in this channel without correspondent changes in riverbeds of rocky rapids. in result, the velocity in waterway may be increased instead of be reduced, the flow condition may also be deteriorated. thus, which branch should be excavated and how to excavate in improving the flow condition of the branch should be further explored
但在分汊河道內，情況較為復雜，在一汊河道內採取開挖措施后，雖然其過水斷面有所增加，局部流速相應降低，但是由於工程后，汊道的分流比將會相應變化，而石質河床一般無法通過沖淤變化以適應水流條件的改變，因此，航道內工程處的流速可能降低，也可能不降反而有所增加，惡化了航道的水流條件。It shows that the water level in the definite reach is lower than that with same discharges before dredging river, the surface slope on upper reaches dredged is enlarged and deposition load on bed is reduced or eroded
主要表現在可以引起一定范圍河段內的水位較挖河前同流量下有所降低，開挖上遊河段水面比降增大，床面淤積量有所減少或發生沖刷。The results of the model tests both in scour and deposit are basically similar with the prototype, and the movable bed tests of some good excavating schemes have been finished
模型經放水驗證，沖淤情況與原型基本相似，並完成了幾個較好開挖方案的動床試驗。Under the condition of applied technology based on internet combined with intellective computational ways and traditional marine condition monitoring, we can construct a new failure diagnosis system ( to develop a distance condition monitoring and failure diagnosis system for main mechanic equipments ) in dredger. it can offer timely credible technical guidance and steps to dredging technician. it is satisfied with the need of dredging security, equipments " condition monitoring and failure diagnosis, maintenance decision of the shipping and its base
將基於internet的應用技術、智能計算方法與傳統的船舶狀態監測與故障診斷技術相結合，在具有首沖功能的300方自航耙吸挖泥船上構造一種全新的故障診斷系統，即開發一套基於網路的挖泥船主要機械設備遠程狀態監測和故障診斷系統，為疏浚作業的技術人員提供及時可靠的技術指導和處理措施，滿足疏浚作業安全、設備狀態監測和故障診斷、實船和基地管理和維修決策的需求，提高設備利用率和管理水平。分享友人
