| 摘 要： | Ｕ型钢可缩性支架的缩动与否，取决于支架卡缆预紧力及搭接部分两端的内力。本文根据Ｕ型钢可缩性支架搭接部分的传力特点和摩擦条件，建立了Ｕ型钢可缩性支架的缩动准则，为支架的力学分析及支护参数的确定提供一种理论根据。

| Abstract: | Whether an U-steel yielding support could yield depend on the pre-screw forces of the camps and the internal forces of both ends at the u-steel overlap parts. Basedon the force transmiting characteristics of the overlap parts and the friction factors,this paper developed the yielding criteria of U-steel yielding support.Which provided a theoreticbasis for the mechanical analysis of the supports and for the determination of supporting parameters. |
