中文拼音 [dòngdetǔliú]
凍地土流
英文
congelifluction-
Because the road line is in mountainous region and heavy hilly area and its surface relief undulates greatly, more slope wash and dilurial layer distribution, there are more harm, for example, island shaped perennially frozen soil, drift ice and so on, which effect the stability of the road foundation
由於沿線地處山嶺重丘地區，地勢起伏較大，坡積物及洪積層分佈較多。故島狀多年凍土、涎流冰等病害較多，影響路基的穩定。During analysis of former edge slope stabilization, it is not especially that affects of freezing - melting eroding to edge slope to slide. the thesis puts forward beiyin channel was destroyed by cold freezing eroding, freezing - melting and runoff of melting snow ect
本文提出北引渠道由於地處高寒和多年凍土地區，在寒冷剝蝕、凍融剝蝕以及融雪徑流等的動力作用下，渠道將發生較為嚴重的破壞。For example the concrete faced rock - fill dam in frigid zone is distinctive in terms of frost resistance and durability, cushion material seepage prevention and frost heave, adaptability of darn filling with season coordination among construction diversion, flood discharge and the whole construction schedule etc. lianhua construction which is situated in mudanjiang basin of heilongjiang province firstly creates the successful record of construction of large - size faced rock - fill dam in frigid zone, a series of internal and external problems not having a precedent to go by have been solved
如在面板的抗凍耐久性、墊層材料防滲和凍脹特性、壩體填築與季節的適應性、導流和度汛與總體進度的協調等方面，寒冷地區混凝土面板堆石壩均有其獨特之處。蓮花工程位於黑龍江省牡丹江流域，首創了高寒地區修建大型面板堆石壩的成功記錄，解決了一系列國內外均無先例的難題。Ice palaces were popular in the soviet union, to which turkmenistan once belonged, but they were built in the freezing cities of the north, far away
冰雪宮殿在前蘇聯非常流行（土庫曼斯坦曾屬於前蘇聯） ，可它們大都建在地凍天寒的遙遠的北方城市。Thaw settlement cause negative friction. this paper base on the thought of " initiative cooling ", aim at three problems existing in common concrete pile used in frozen soil, a new type of pile is proposed to overcome the disadvantages of the classical pile used in frozen soil. pile body within active layer is fluted and refilled with porous materials such as gravels and ballasts, convection will be occur and then thermal exchange inside porous material in winter while only heat conduction exists in summer, as a result the soil around flutings will be cooled, so the top line of permafrost will be drive up
本文基於「主動冷卻」地基的思想，以及針對凍土地區普通混凝土樁存在的三大問題，提出了一種新型樁的設計思路，運用數值模擬試驗手段對其冷卻機理與加固機理進行了系統研究，即在凍融活動層的深度范圍內，在混凝土樁身的表面刻槽，修築完時槽內填充碎石、塊石等多孔介質，通過外界大氣溫度的自然波動下多孔介質在冬季時存在的對流換熱機制，而在夏季只存在熱傳導，來達到主動冷卻樁周凍土和抬升凍土上限的目的。Adaptability of dam filling with season and coordination among construction diversion, flood discharge and the whole construction schedule should be taken into consideration. the choose of dam site, layout of the multipurpose project, design of concrete faced rockfill dam, construction and prototype observation are covered in this paper
如在混凝土面板的抗凍耐久性、墊層材料防滲和凍脹特性、壩體填築與季節的適應性、導流和度汛與總體進度的協調等方面，寒冷地區混凝土面板堆石壩均有其獨特之處。分享友人
