The invention relates to a super-long reinforcement cage hoisting point optimization design and stress calculation method, which belongs to the technical field of foundation underground structure construction, and comprises the following steps: establishing a reinforcement cage hoisting point total coordinate system and two reinforcement cage hoisting point local coordinate systems, which are suitable for four-point hoisting of a reinforcement cage, the method comprises the following steps: carrying out independent stress calculation according to each section of branched rope at the bottoms of two steel wire ropes, calculating the counter force of each hoisting point in combination with the movement track calculation of the bifurcation point of the steel wire ropes, then calculating the bending moment of each hoisting point, and obtaining the point with the minimum absolute value of the maximum positive and negative bending moments according to the algebra, namely the optimal hoisting point. The method has the effects of improving the calculation speed of the bending moment value when the hoisting point of the reinforcement cage rotates and being more accurate.

    本申请涉及一种超长钢筋笼吊装点优化设计及受力计算方法,属于基础地下结构施工的技术领域,包括以下步骤:建立一个钢筋笼吊装点总坐标系和两个钢筋笼吊装点局部坐标系,适用于钢筋笼的四点吊装,根据两个钢丝绳底部岔开的每段分绳进行单独受力计算,以及结合钢丝绳分叉点的运动轨迹计算,先计算出各吊装点的反力,再计算各吊装点的弯矩,根据代数得到最大正负弯矩绝对值最小的点即为最优吊点。本申请具有提高钢筋笼吊装点旋转时的弯矩值计算速度并更加精准的效果。
