另外，試驗結果還表明：在一定的拉應力下，插入角鋼與混凝土之間的粘著力能通過插入角鋼與混凝土之間的位移反映出來。這是由於橫斷面的收縮，使得粘著應力明顯降低，即泊松比效應。To solve the inaccuracy problem caused by the two existing methods ( average end - area method and prismoidal method ) used for the calculation of roadway earthwork volume, this paper puts forward a new concept of the 3 - dimensional algorithm that takes all the roadway geometric design procedures as a kind of geometrical operation between the ground model ( original terrain model ) and the roadway model ( designed model ) under certain constraints, and then presents a complete 3 - dimensional algorithm of roadway earthwork volume as well as its executable computer program. the algorithm benefits from the re - triangulation technique of constrained delaunay triangulation ( cdt ), which can yield a true volume value theoretically. through a number of practical tests covering varied intervals between adjacent cross sections, it is proven to possess a higher accuracy compared with that of traditional methods. all the work involved in this paper indicates that the 3 - dimensional calculation of roadway earthwork volume is feasible, more accurate and should have further application in practice

U ）試驗現象從試驗中可以觀察到所有粘結試件的破壞都是從粘結面斷開，破壞面比較平直。但具體情況與所受溫度不同而有關。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。In this thesis, first, reasons and factors for the stability of loose rock dams were summarized according to the field surveys and certain expert ' s experiences. then, researches on block stability problems were reviewed, and according to the relationship between grain size and incipient velocity, it is found that the block weight is in direct proportion to 6 - 9 power of incipient velocity, and 50 % increase of the velocity will result in about 40 times change of the block weight. after that, experiments were conducted in a flume, focusing on the relationship between incipient velocity and some main factors including block weight, water depth over the dam, cross - section size, block material and river bed material
