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。 -
Abstract : in this paper, a kind of technological scheme for one - step precision forging spur gear with large module is put forward by using positive friction role. experiment, in which commercial pure lead is taken as test material, is done in the special die designed, and force vs. stroke curve is recorded. it is shown that positive friction role can efficiently make a contribution to the filling of the tooth cavity, but increase forming force
