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。Combined with practical data of shannxi lin hekou hydropower plant, the temperature filed of m and n schemes during construction and operation are simulated and analyzed. the isoline map of stable temperature field of the arch crest girder section and the vertical section in the center of arch dam, the isoline map of unstable temperature field of the arch crest girder section and the vertical section in the center of arch darn during construction and operation and the maximal and minimal temperature value during construction and operation are provided. the distribution law of temperature in the dam and the form reason of high - temperature zone are analyzed and the effect and feasibility of cooling and the zone of cooling are discussed
結合陜西藺河口水電站工程實際資料，對m方案和n方案溫度場進行了施工期和運行期全過程模擬計算分析，給出了拱冠梁剖面和壩體中心縱剖面準穩定溫度場等值線圖以及施工期、運行期拱冠梁剖面和壩體中心縱剖面非穩定溫度場等值線圖，提供了施工期逐月和運行期每年最高、最低溫度等成果，分析了壩體溫度分佈規律以及高溫區形成的原因，並探討了預埋冷卻水管的效果和可行性以及預埋冷卻水管的區域。Confirm a seat number : here special remind is, still must call to determine a seat number to airline before setting out 3 days ago, otherwise your seat number is probable because never affirm, and be cancelled automatically by airline, travelling especially busy season, more want tread lightly, just won ' t " carelessness breaks jing zhou ", will good grab easiness seat number not easily, submissively lets a person
確認機位：在此非凡提醒的一點是，出發前三天前還須打電話至航空公司確定機位，否則你的機位很可能因為不曾確認，而被航空公司自動取消，尤其在旅遊旺季，更要小心處理，才不會大意失荊州，將好不輕易搶來的機位，拱手讓人。Aesthetic appearance is one of the most important criteria used by consumers in judging clothing wear performance. bagging is a kind of three - dimensional residual deformation that deteriorates garment appearance during wear and caused dissatisfaction. to understand the psychophysical mechanisms of fabric bagging perception, a method of subjectively evaluating this behavior is developed by using a series of photographs taken from bagged fabric samples. both ranking and rating scales are used as the psychological scales. the two scales are highly correlated with each other, but the rating scale provides more information than the ranking scales and can indicate perceived differences between fabrics. a linear relationship between subjective perceptions and measured residual bagging height shows that perception of fabric bagging follows stevens ? power law. residual bagging height contributes up to 94 % of the total variance in the perception of fabric bagging. the rest of the variation may be attributed to anistropic behavior during the bagging process
美觀是消費者日常服裝穿著功能中最重要的指標之一.起拱是一種外衣穿著中引起變化，令人不滿的三維殘余變形.一種主觀評價方法是從一系列起拱織物的照片來理解心理物理學規律，採用優劣排序等級和優劣評判等級兩種方法用於心理評價標度.這兩種等級互相間緊密相關，但評判等級比排序等級包含更多的信息，可以更好地區分出兩種織物間的差異.主觀評價結果與測量得到的殘余起拱高度之間線性相關，表明了織物起拱特性符合斯特藩指數定律.殘余起拱高度對織物起拱特性總方差的貢獻在94 %以上.其它可能是起拱時各向異性因素引起的Based on theory of big flexibility defective close columnar shell, use adding partition board to resolve the partial buckling problem in partially cfst arch bridge ' s hollow steel tube segment. the formula of how to confirm the space between partition boards was deduced to content whole and partial buckling
在大撓度有缺陷閉合圓柱殼體局部穩定理論基礎上，提出採用增設橫隔的辦法以解決部分灌注鋼管混凝土拱橋中空心鋼管段的局部穩定問題，並導出了在同時滿足鋼管整體和局部穩定性的前提下，需增設橫隔的間距的公式。Combined with that the influence of the prestressed tendon layout on mechanics characteristic of three - span prestressed concrete deck arch bridge is taken into account in these methods, and demand of internal force and displacement in design is satisfied by using upward and downward eccentric layout of prestressed tendon
這些設計法針對該類橋型的特點，利用在拱頂梁中分別布置一定數量的上下偏心的預應力筋來優化結構的內力和滿足各部分的位移限制要求。分享友人
