  2. The results indicate that the stability for bifurcation point equilibrium configuration and post - buckling equilibrium path of roof strata can be revealed and an effective method for determining displacement field of imperfection structure can be provided by using initial post - buckling theory
    应用初始后屈曲理论可揭示浅埋煤层长壁开采顶板岩层的分叉点平衡构形及后屈曲平衡路径的稳定性,是确定非完善结构位移场的一种有效方法。
  3. 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
    摘要根据浅埋煤层顶板岩层的赋存特点和长壁开采时关键层的变形破断特征,应用初始后屈曲理论探讨了开采过程中顶板关键层的后屈曲性态,得出了老顶初次来压时顶板的临界载荷和破断步距,确定了顶板破断后的极限下沉量和回转角,并以神东矿区大柳塔1203工作面为例给出了工程实例。
  4. According to the elastic bucking theory this paper reviews and compares the calculations that such member bend around the reat axis and the hollow axis as well as bend with torsion around the hollow axis . here this paper presents a formula of calculating b used in with the h - shaped anglicizing element . meanwhile , this paper deduces out a formula of calculating b . by , which the member could be controlled to only buckle around the real axis
    本文根据弹性屈曲理论对双肢格构式单轴对称缀板柱绕实轴、虚轴以及弯扭屈曲进行了计算分析和比较,提出了绕虚轴侧向屈曲的换算长细比_ ( oy ) = ( y ~ 2 + l ~ 2 ) ~ ( 1 / 2 )中的值用h计算单元指出的计算公式,同时推导出了单轴对称缀板柱只出现绕实轴弯曲屈曲的最小肢间间距b 。
