這些早期的加油機使用的是一種笨重的加油系統，受油機必須象空中格鬥那樣與受油機建立起連接航線然後用絞車牽入軟管建立連接。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。3 - wire strands with tensile strength of 1570 mpa were collocated in the lower precast concrete slabs of superposed floor. the manner of reinforcement lap and other detailing were brought forward. plane dimensions of the tested floor are 9m and 12m, and height is 180mm
本論文通過對前期試驗的分析總結，選用1570mpa的三股鋼絞線作預制底板的預應力鋼筋，提出了合理的板側橫向鋼筋搭接方式和其它構造措施，並按照現行規范設計並製作了試驗結構，樓蓋平面尺寸9 12m ，樓板厚度180mm 。分享友人
