1·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.

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。

2·After being set state load, optimized timbering adds support yielding deformation, increases the load-carrying ability and improves the effect of controlling the surrounding rock.

在给定初始支撑强度的前提下，加大支架的让压变形量，提高支架承载能力，大大改善了矿工钢梯形支架控制围岩的效果。

3·The distinguishing features of the paper are selection of oblique strip and loading transmission, negative yielding line in irregular slab with simple supports, point support and shear split of slab.

本文的主要特点为有料向板条的选取及荷载传递、简支不规则板的负弯矩裂缝线以及点支承板条和板的剪切劈裂问题。

4·The support materials can provide huge consolidation strength for rocks in the process of control before and after yielding fracture, which has potential support in minerals and rocks.

支护材料在岩层屈服断裂前和断裂后的控制中，可提供巨大固结岩层的能力，对矿岩有着潜在支护能力。

5·Abstract: Due to high stress and large deformation of deep roadway surrounding rock, the support system must have high-strength yielding characteristics.

摘要深部巷道围岩的高应力、大变形特点，要求支护系统具备高强让压的特性。
