凍脹地基
英文
heaving bottom-
Thermal performance of buildings - thermal design of foundations to avoid frost heave
建築物的熱性能.地基防凍脹的熱設計Frost heaving analysis of corrugated pipe culvert without foundation in permafrost region
多年凍土地區無基波紋管涵洞凍脹分析The test obsvervation include air temperature, ground temperature, foundation moisture, freeze depth, freeze capicity, freeze residual capicity, groundwater table and shape transform of canal lining, etc. throught systemic observation, analysis of impact about each factor on fundation freeze capicity, evaluate effect on anti freeze of various canal lining, comparison on technology and ecnomic of different method, a kind of main canal lining format is been recommended to engineering practice with siutable to ningxia local feature, fufilling the need of main canal safey i application, economic and practical, that is using polystyrene plate laying under concrete slate and grit taking replace of filling layer and optimizing design
試驗觀測內容包括氣溫、地溫、基土含水量、凍深、凍脹量、凍脹剩餘量、地下水位和砌體外觀變化等項目。通過系統的觀測，分析各因素對基土凍脹量的影響，評價各種襯砌型式的防凍西安理工大學工程碩士專業學位論文脹效果，並進行技術和經濟綜合分析比較，推薦出了適合我區特點、滿足乾渠安全運行、經濟實用、防凍脹效果好的乾渠防滲襯砌型式，即混凝土板下鋪設聚苯乙烯板和砂礫石換填層結構型式，加以優化設計，用於工程實踐。The continual freezing and expanding, melting and submerging and melting and sinking of roadbed are the main problem on the building and maintaining of road in frozen earth area
路基周而復始的凍脹、融沉和熱融滑塌是凍土地區道路建設和維護所面臨的主要難題。The analysis on season ' s frost swelling and subgrade stabilizations
季節性凍土地區路基的凍脹與融沉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。In permafrost areas, thaw - settlement problem is the main content for the frozen harmfulness study ; in the seasonally frozen soil areas, frozen expansion problem is considered most in order to prevent and father the frozen harmfulness for the groundwork, the thaw - settlement index is thought little relatively, but it has been investigated from the data of frozen harmfulness, the thaw - settlement behavior still has an active effect on the construction stability in the seasonally frozen soil areas
在多年凍土區，融沉問題是凍害研究的主要內容;在季節凍土地區，為了防治地基凍害問題，考慮最多的往往是凍脹問題，對融沉指標一般考慮的比較少，但是根據調查凍害資料來看，融沉性在季節凍土地區的建築物穩定性方面的應用仍然具有積極的意義。In the area of seasonal frozen region, the road takes place the cycle of freezing and thawing variety with the season, the mainly disease harm generating from this is the frost heave and frost boiling etc. . the disease harm belongs to the heat transfer problem, but the effective measure to prevent and cure the frost boiling has something to do with the gradient of temperature and humidity
在季節性凍土地區，道路隨季節交替發生凍融循環變化，由此產生的病害主要是凍脹和翻漿等。病害的形成歸根結底屬于熱質遷移問題，而防治凍脹與翻漿的有效措施無不與溫度和濕度有關，搞清冬季凍結過程道路結構體系溫度、濕度及應力的狀況，是正確設計路基路面，防治凍脹和翻漿的先決條件。分享友人
