buckling breaking 中文意思是什麼
buckling breaking
解釋
壓曲破壞-
In accordance with the occurrence behavior of roof strata and the fracture characteristics of key stratum in shallow seam longwall mining, studied post - buckling behavior of roof key stratum in the process of mining by using initial post - buckling theory, which derived a critical load and a breaking span of the main roof during the first weighting, determined the final subsidence and the maximum rotation angle for broken key stratum, and presented an application with the example of daliuta 1203 face
摘要根據淺埋煤層頂板巖層的賦存特點和長壁開采時關鍵層的變形破斷特徵，應用初始后屈曲理論探討了開采過程中頂板關鍵層的后屈曲性態，得出了老頂初次來壓時頂板的臨界載荷和破斷步距，確定了頂板破斷后的極限下沉量和回轉角，並以神東礦區大柳塔1203工作面為例給出了工程實例。 -
In this paper we study the transverse stiffeners of the thinned - web beam bearing several concentrated longitudinal strain actions. thinking of using post - buckling strength of web plate, we study some facts about tran sverse stiffeners including strain ability, condition of breaking, calculation of strength and stabilization of the stiffener bearing regional load action
本文對受多個集中荷載作用的薄腹板梁的橫向加勁肋進行了研究，分析了利用腹板屈曲后強度時，橫向加勁肋的受力狀態、破壞機理，以及加勁肋局部承壓的強度計算公式和穩定計算方法。 -
It is pointed that the thick unconsolidated layers above roof have effect on post - buckling behaviors of key stratum, the equilibrium path of roof is unstable from breaking to final subsidence
研究發現，頂板上覆厚鬆散沙層對關鍵層的后屈曲性態有影響；頂板從破斷至極限下沉其平衡路徑不穩定。
