中文拼音 [gǒngzhàng]
拱脹
英文
blow up-
According to this, the temperature field stress field and autogeny body - expand - deformation field of yangchun arch dam during construction arid operation period are analyzed, thus many significant conclusions are got for reference
由此，模擬分析了陽春拱壩施工期和運行期溫度場、自生體積膨脹變形場及應力場，得到了一些有參考意義的結論。The calculation modes of the coefficient of shrinkage and creep of the bulgy core concrete in steel tube are discussed. based on a few reasonable hypotheses and the stress - strain relation of concrete acquired by the " adjusting valid modulus depending on load time " method, a compact formula is reasoned out, which is applied to calculate the equivalent elastic modulus of the bulgy core concrete considering the affection of shrinkage and creep. so, the analysis of the affection on cfst arch bridge by shrinkage and creep can be progressed by pole - girder fem, further more, the analysis precision is quite high
本文還對核心膨脹混凝土特殊的收縮、徐變系數計算模式展開了探討，在合理的假設前提下，採用「齡期調整的有效模量法」得到的混凝土的本構關系，推導出鋼管內核心混凝土在考慮徐變影響后的等效彈性模量計算公式，並以此為基礎採用桿系有限元方法來對鋼管混凝土拱橋進行較高精度的收縮徐變分析。The cyclo - hoop effect which steel tubular has exert to the concrete shows the character of heterogeneous in the arch rib section, the same to the axial direction. the paper verifies the change of the material poisson ration and the concrete grade will make the cyclo - hoop effect obvious alteration, the change of the cyclo - hoop effect and the stress redistribution of the section produced by the shrinking and creeping of the concrete and the expensive concrete on the section
在鋼管混凝土拱肋斷面上，鋼管對內填混凝土的環箍效應具有非均勻性，在拱軸方向上環箍效應也呈現非均勻性。驗證了材料的橫向變形系數、混凝土標號等參數的變化將引起環箍效應的明顯改變；混凝土的收縮、徐變和膨脹混凝土的應用導致鋼管混凝土的環箍效應發生變化並使截面的應力發生重分佈；並總結了其變化的基本規律。Taking into account hong kong s warm and humid weather, carpenters purposely leave narrow gaps between floorboards to allow for expansion
由於香港天氣潮濕溫暖，工人鋪地板時會在木條之間預留幼縫，以供日後膨脹之用，避免拱起變形。Testing methods for bagging of woven and knitted fabrics
機織物及針織物局部拱脹的試驗方法Textiles. woven furnishing fabrics. determination of bagging
紡織品.傢具裝飾用機織織物.拱脹性的測定Based on several actual cases, the temperature control measures for roller compacted concrete ( rcc ) gravity dam and arch dam such as structural jointing for construction ; lowering of concrete placing temperature ; water pipe cooling ; surface insulation ; inclined - layer placing etc., the measures to improve the material properties i. e. the application of micro - expanding concrete ; enhancement of material crack - resistance property and the requirement for the simulative analysis on both the temperature field and stress field as well as some problems concerned are summarized herein on the basis of the analysis on the material properties ; construction characteristics and the changing characteristics of the thermal stress of roller compacted concrete
摘要從碾壓混凝土的材料特性、施工特點、溫度場溫度應力的變化特點入手，結合幾個工程總結了碾壓混凝土重力壩、拱壩的分縫方式，降低澆築溫度、水管冷卻、表面保溫、施斜層碾壓等溫控措施，採用微膨脹混凝土、提高材料抗裂性能等改善材料性能措施及碾壓混凝土溫度場、應力場模擬分析的要求和應注意的問題。3. with the consider of one mgo concrete arch dam in guangdong province, its construct course was simulated and its thermal field, autogenous volume expansion field, strain field, stress field and displacement field were also analyzed. at the same time, the simulated analysis theory and accuracy and rationality of the program were validated in comparison with the prototype observation data
3 、結合廣東某外摻mgo混凝土拱壩，對其施工過程進行了模擬，完成了壩體的溫度場、自生體積膨脹場、應變場、應力場及位移場的實時模擬分析，同時結合原型觀測資料的分析，對模擬分析成果進行了驗證。分享友人
