2 ) the structure elements should be laid out symmetrically and uniformly when designing steeve - arch structure, what ' s more, the reasonable selection of section geometric size near the arch foots of first beams is paid attention to and the arrangement difficulties of steel bar due to the big eccentric pressures 2, the analyses of anti - seismic features on transverse direction of the aqueduct l ) the method of adjusting the elements " mass can be harnessed in order to even the layout of seismic loads
2 ）設計吊桿式拱架支承結構時，各部分構件應當均勻對稱布置。另外，還應注意頭道梁拱腳附近截面的尺寸擬定，克服地震內力造成的大偏心受壓狀態給結構配筋設計增加的困難。 2 、橫槽向抗震性能分析1 ）可利用調整構件質量的方法，使得結構的某些構件的地震荷載分佈均勻一些。 -
It also has important reference value for the similar construction. by the safety and seismic evaluation of this aqueduct bridge, it has shown that ( 1 ) besides the structure of this aqueduct bridge was basically unharmed without some flake of concrete cover and revealing stirrup, its intensity basically reached the need of primary design. ( 2 ) from the side of carrying capacity, rib arch could satisfy the needs under the action of wind and earthquake, but some individual frame crossbeams and most rib arch tie beams could n ' t satisfy the need
通過對東滑峪渡槽進行安全性能和抗震性能評估后表明： （ 1 ）渡槽除肋拱頂面有保護層剝落、箍筋外露，結構基本完好，其強度基本達到西安理工大學工程碩士專業學位論文原設計的強度要求； （ 2 ）從承載力方面看，在風荷載、地震作用下，肋拱基本滿足要求，個別排架橫梁不滿足要求，肋拱連系梁普遍不滿足要求；計入水平橫槽向地震作用的工況為設計控制工況。 -
On the contents of two sides abovementined, this paper attempts to do some initial researches from three angles as follows : 1, the analyses of anti - seismic features on longitudinal direction of the aqueduct l ) the seismic longitudinal effects are small. the vibrant characters are decided from the structure integration and rigidness of piers and main arch - ring of the aqueduct, so the following measures should be taken in order to weaken and isolate seismic influence : properly broadening the section sizes and adopting the high class concrete, lowering the height and barycenter of building, setting hoop steel bars so as to increase the plasticity of the concrete which can absorb the seismic energy and prevent the damages due to stress centralization on the linkages and changing place
本文試圖就上述的這兩大方面的內容，從以下三個角度進行了初步研究： 1 、縱槽向抗震性能分析1 ）湯峪河吊桿拱支承結構的縱槽向地震效應較小；吊桿式拱架結構動力特性取決于槽墩和主拱圈的剛度，以及結構的整體性，故適當加大構件截面尺寸或提高砼標號，盡量降低結構的建築高度和重心，在構件連接和變截面處增設梗脅，按照約束混凝土的要求來加強箍筋的配置，增加砼的延性，以克服地震時構件連接和變截面處的應力集中造成的坡壞，並吸收大量的地震能量，從而起到隔震，減震的效果。 -
On the mrp, the truss arch aqueduct is comprehensively researched in this paper, including its structural characteristic, structural calculation and reliability analysis
本文結合南水北調中線工程，對下承式空腹桁架拱排水渡槽的特點、結構計算以及結構的可靠性進行了較全面研究。 -
The prestressed drainage aqueduct of through open - web truss arch structure is widely applied to cross the main canal of the mrp. it is important and significative to study the aqueduct ' s structure design and reliability thoroughly
預應力下承式空腹桁架拱渡槽在總乾渠排水建築物中被廣泛採用，其結構設計和安全可靠性是一個非常重要且值得深入研究的問題。 -
For example, no - supporting elements should be made of light material which attracts less seismic loads. 2 ) generally speaking, seismic combined maximum loads of aqueduct transverse direction is less than 100kn, which present joints near the arch - foot sections
2 ）總的來看，各質點橫槽向的地震總名義合外力不大，最大值不到100kn ，且發生在支座附近緊臨拱腳的節點上。 -
The comparative analysis is made firstly, which shows that the truss arch aqueduct can be built on the weak foundation and is also satisfied with the demand for large span length and the great discharge ability, so the type of aqueduct is a better for the project. then the finite element program ( super sap93 ) is applied to the structural analysis of the space structure
