凍脹作用 的英文怎麼說
中文拼音 [dòngzhàngzuòyòng]
凍脹作用
英文
frost heaving-
Following is the factors ideating with the surface of old concrete in different way ( including brushing surface, chiseling surface, cleaving surface ), adherence agent ( including cement slurry, cement sand slurry, cement slurry with the u expansion agent ), the freeze - thaw circulation times and air - entraining. as a result, we found that the roughness influence on the adhesion capability of the new on old concrete to a large degree. the larger rougeness is, the larger the splitting tensile strength on the adhension face is. the kind of adhesion agent is also influence on the adherence capability of new on old concrete. the circulation times of freez - thaw have a large influence on the splitting tensile strength of adherence face of new on old concrete. the analysis of tests give some advices to the practical engineering
主要考察了老混凝土表面不同處理方式（刷毛面，鑿毛面，劈裂面） 、界面粘結劑類型（水泥凈漿，水泥砂漿， u型膨脹劑水泥漿） 、凍融循環次數等對新老混凝土粘結面劈拉強度的影響，以及凍融作用下新混凝土加氣對粘結面劈拉強度的影響。試驗結果表明，粗糙度對新老混凝土粘結性能有重要影響，隨著粘結面粗糙度的增大，粘結面劈拉強度不斷增加；界面粘結劑類型對新老混凝土粘結性能有一定影響，在凍融作用下， u型膨脹劑水泥漿粘結效果不如水泥凈漿和水泥砂漿；凍融循環對粘結面劈拉強度有較大影響，加氣能明顯改善新老混凝土粘結面的抗凍能力。I have therefore always concerned myself with how government manages these investments with an aim to increasing its value. i have previously expressed my concern about the tendency for various government departments to upsize rather than downsize in the face of economic slump. mr. tsang responded by saying at the press briefing after his budget speech, that he had already asked government departments where the " user pay " principle applies to freeze their charges
在預算案公布后的簡報會上，曾司長在答覆本人表示關注政府部門在經濟降溫的時刻，不但不作節約，反而有逐漸不斷膨脹的趨勢時，表示已要求那些需要持著用者自付原則的收費部門，凍結收費，這種手法無疑是對癥下藥了。One of the most important one is the piles on the poor geological conditions such as saturated permafrost soil or underneath ice layers, such as : 1. frozen soil beside piles is thawed caused by construction and cement hydrate heat, it need quite time to recover freezing again ; 2. frost heaving sometimes pull up piles ; 3
凍土地區樁基普遍存在著： 1由於施工、水泥水化等造成樁周凍土融化，需相當長時間內才能回凍； 2樁周凍土凍脹對樁的「冷拔」作用往往將樁拉斷； 3樁周凍土融沉引起負摩阻力。Ordinary it takes over 30 % cost of total irrigation buildings. in seasonal frozen soil area, frozen heave produces frozen - heave forces on the slab - foundation. it often make the slab - foundation damage due to bending, twisting and growth - up if the construction is build following non - frozen soil design methods
季節凍土區涵閘工程是水利工程建設中常見的一種結構，一般占水工建築物工程造價的三分之一以上，在季節凍土區由於土凍結后產生的凍脹，對板基作用有凍脹力，所以按照融土壓力設計的板基經常發生彎曲、扭轉、上抬等破壞。To keep membranes in wet state, do not immerse them in stale water for long time. water should be changed periodically. avoid mildewing in summer and freezing in winter
部分作用膜儲存時最好經清水浸泡膨脹、逐張曬干后保存、如濕態保存時不宜在死水中長期浸泡，應定期換水，夏秀防止發霉，冬秀防止凍裂。The variation of stress and deformation fields in the freezing zone of an earth embankment is analyzed, and the effect of different frost - heaving zones on the deformation and stress of embankment surface is calculated
分析了土基范圍內凍脹帶對路基應力場和變形場的作用，並計算了不同凍脹帶范圍對路基頂面變形場和應力場的影響。分享友人
