文摘:本文以石門拱壩為例，說明基於原觀資料進行拱壩及其基礎的綜合分析的方法.內容包括：在反演擬合滲透系數和壩與基巖接觸面的抗拉強度參數的基礎上，進行壩址區三維滲流場分析、拱壩與基礎的三維線彈性、彈塑性力學分析，並用多種方法探求了拱壩抗滑穩定安全系數Secondly, the effect of transverse deforming on the property of the wedge pressing was studied. the results showed that : the wedge pressing stock with the transverse deforming amount of 10 % acquired the best performance. the highest density got the biggest rate of slope while with the amount of 30 % the curve was more some special structure and performance as following : the large porosities was crushed into small or linear ones with the high - direction deformation amount of 20 % ; as the increasing of the high - direction deforming, the particles got a further deforming, the porosities got a further crushing, the small porosities were mergered by the large ones and the former then disappeared ; when the amound reached 60 %, the quantity of the porosities would obviously decrease which made the materials compact, the microstructure more uniform and the density and hardness curves more horizontal, the relative desity could reach 99. 7 %, the tensile strength b of the as - compacted samples reached 408mpa with the yield strength s teached 289mpa and the elongation percentage reached 13. 6 %. in addition, the microstructure of the wedge pressing stock under the pressing temperectureof 450 was uniform, the porosities and the boundries of the grains basically disappeared and the conjunction between particles was great
採用雙向楔形壓制，大尺寸噴射沉積5a06鋁合金楔壓坯的組織和性能變化具有如下特點:當高向變形量為20 %時，大的孔洞變形破碎為小的孔洞，或呈線狀孔;隨著高向變形量的增加，顆粒進一步變形，孔洞進一步破碎，大孔「吞併」小孔，小孔塌陷並逐步消失;當高向變形量達到60 %時，孔洞量大為減少，材料基本緻密，組織趨于均勻，楔壓坯料的密度、硬度變化曲線接近水平線，坯料的相對密度達99 . 7 % ，抗拉強度_ b = 408mpa ，屈服強度_ （ 0 . 2 ） = 289mpa ，延伸率= 13 . 6 % ;對比其它的壓制溫度，在450楔形壓制的坯料組織均勻，孔洞及顆粒邊界基本消失，顆粒之間冶金結合良好。Because of the former anchorage systems designed according to matching 1860mpa strength strands in the beginning of 90 ", they can not be suitable any more for the super strength strands with 2000mpa. therefore, some accidents occurred such as strands sliding and broken when tensioning. in addition, the advantages of the new materials as their high mechanics performance are not be used completely as the prestressing structures was designed as per the 1860mpa strands, which will result in the waste of materials, in view of the above - mentioned facts, by means of analyzing the development of anchorage systems home and abroad, in connection with the characteristics of the super strength strands ( 2000mpa ), this topic made a research on hvm15 anchorages by theoretical calculation and finite element analysis, and also on the manufacturing process and test
隨著預應力技術的發展和冶金工業冶煉技術的不斷進步，預應力鋼絞線的強度不斷提高，由原來1470mpa提高到1860mpa ， 90年代末期已出現了2000mpa超高強鋼絞線，而原來的是在90年代初期按抗拉強度為1860mpa的鋼絞線標準設計的，因此，原有的錨具已不能適應現有超高強度2000mpa的鋼絞線強度要求，在工程中出現了斷絲滑移現象，同時，在使用和設計時仍按1860mpa鋼絞線的指標進行設計應用，沒能充分發揮材料的力學性能，造成材料浪費。Surveyors use inspection instrument ( single - yarn strength tester ) toexamine the anti - tensility of the medical gut suture and the seam of needle and suture of the suture with needle. all the teste attained the state standard. the safcty and trustiness of the quality is ensured
