frozen heave 中文意思是什麼
frozen heave
解釋
凍脹-
Through a systematic research, the author enter to provide the theoretical basis for selecting reasonable index of normal frozen - heave forces and the technology for preventing and controlling frozen damage
通過系統研究，渴望為季節凍土區涵閘類水工建築物基礎板的設計部門提供法向凍脹力值的設計指標，以便做到基礎的合理淺埋和進行抗凍脹設計。 -
The aim of this thesis studies frozen - heave forces on culvert brake slab - foundation. first, it introduces the reasons and types of frozen damage of the slab - foundation in seasonal frozen soil conditions. secondly, the experimental studies of frozen soil mechanics were decided in order to revolve frozen - heave forces on the slab - foundation
本論文以涵閘平板式基礎作為研究對象，首先探討了平板基礎凍脹破壞的原因及破壞類型，並圍繞涵閘工程平板基礎的凍脹力進行了工程凍土力學方面的試驗研究。 -
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。 -
The indoors experimental results show the influence of soil density, moisture, permeability and restrain on the frozen - heave forces. from year ' s observation in - situ, the field data supports the relationship of foundation area, embedded depth and superimposed load with normal frozen - heave force
通過野外現場的試驗的觀測，初步掌握了基礎法向凍脹力與基礎面積、基礎埋深、附加荷載等因素之間的關系以及平板基礎所受凍脹上抬力各組成部分之間的相互影響規律。 -
On the countermeasures against road frost boil and heave in the seasonal frozen region
季節性冰凍地區公路凍害的防治對策 -
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。 -
The study on frost heave is always a hot subject in the frozen soil research field, it has great difference in frost heave characteristics to each kind of soil
土體凍脹一直是凍土研究領域的熱門課題，不同性質土的凍脹特性有很大差異。 -
