非对称U型钢支架内力计算

Non-symmetric U-shaped Steel Bracket Internal Force Calculation

分析了U型钢支架的受力情况,利用虚功原理及莫尔定理给出了其在非对称围岩作用力下进行非对称支护后的内力计算方法和具体公式。并给出了一个具体算例。

The article analyzes the load stress of the U-shaped steel bracket and gives the internal force calculation method of the U-shaped steel bracket after it being shored non-symmetrically under the non-symmetric surrounding rock stress and the specific formula by using the principle of virtual work and Moore theorem. At last, it shows a specific example.
