一片靜寂突然籠罩了這間幽深的拱頂斗室。是溫暖和沉滯的空氣帶來的靜寂。It has powerful competitive capacity and huge application market in china for all of its advantages, such as strong spanning ability, light dead weight, rapid construction speed, beautiful configuration etc. nevertheless, for some reasons, its research work lags behind its engineering practice seriously, affecting its further application and dissemination
拱型波紋鋼屋蓋是一種新型的空間鋼結構，具有跨越能力大、自重小、施工速度快、造型優美等突出優點，因而在我國有著強大的競爭力和廣泛的應用市場。但由於種種原因，無論在國內還是國外，其理論研究都嚴重滯後於工程實踐，嚴重影響了結構的進一步推廣和普及。Abstract : for high arch dams in valleys with the characteristics of high water head, large discharge and large power, the problems of energy dissipation and scour prevention are serious. based on scientific studies, new comprehensive measures are proposed, including dispersion of discharge to waken wallop of the current, and reinforcement of riverbed to enhance the erosion - resistance. the measures can be used to solve the problem of energy dissipation properly. a typical layout scheme has been proposed in which slotted bucket with diversion teeth, double deck with pores, and cushion pool are considered practice has proved that the scheme is reliable and the effect of energy dissipation is obvious
文摘:高拱壩泄洪消能的特點是壩高落差大，流量大，功率大，位於河谷狹窄地區，泄洪消能與防沖問題突出.經科學研究，採用「分散泄洪，削弱水流沖擊力，加固河床，增強河道抗沖能力」的綜合治理措施，較好地解決泄洪消能布置問題.提出了表孔大差動坎加分流齒、雙層多孔、水流撞擊、下設水墊塘聯合消能的典型布置方案，經實踐證明，方案可靠，消能效果好When there is original stage support only, the load ratio of surrounding rock gets more and more bigger with the increasing of crust stress, correspondingly, the load ratio of initial stage support gets smaller. when the initial stage support and the second support act each other, the load ratio of surrounding rock is more than fifty percent, and it has little change with the increasing of crust stress. the whole analysis of the surrounding rock and support shows that the bottom arch of liner and the feet of liner have serious stress concentration, so do the sidewalls and the foot of a wall of the surrounding rock
通過屈曲理論分析結果對比表明，彈性屈曲和突變失穩分析的結果比非線性屈曲分析的結果要大得多，非線性分析由於考慮了材料非線性和幾何非線性，因而結果與實際接近實際；當只有初期支護時，隨著地應力的增加，圍巖的荷載分擔率增大，相應地，初期支護的荷載分擔率就減小了；當有初期支護和二次襯砌共同作用時，圍巖的荷載分擔率在50以上，這一分擔率隨地應力的增加其變化不大；支護和巖體的整體分析表明，襯砌底拱及拱腳處應力集中嚴重，隧道巖體側墻及墻角圍巖的應力集中也較大。分享友人
