为了提高挂篮法施工混凝土连续梁合拢的效率和强度,进行混凝土连续梁合拢顺序调整优化,改善施工工艺在线性荷载下分析混凝土连续梁的本构模型,根据混凝土梁结构的剩余抗拉强度进行双排和单排梁结构的锚杆布置。结合混凝土梁结构的最大应变强度进行荷载加载控制,建立线性荷载模型进行挂篮法施工中的应力评估,根据应力强度进行连续梁合拢顺序调整,采用有限元模型进行混凝土连续梁的网格化静力测试,实现挂篮法施工优化。实验结果表明,采用该方法进行挂篮法施工混凝土连续梁合拢顺序调整,能有效提高混凝土连续梁的强度,提高施工效率的同时,改善施工质量。
In order to improve the efficiency and strength of concrete continuous beam closure by hanging basket method,the closure sequence of concrete continuous beam is adjusted and optimized.The constitutive model of concrete continuous beam is analyzed by improving construction technology under linear load.According to the residual tensile strength of concrete beam structure,the anchor rod arrangement of double row and single row beam structure is carried out.Combined with the maximum strain strength of concrete quantity structure,load loading control is carried out.The linear load model is established to evaluate the stress in the construction of hanging basket method.According to the stress intensity,the closure sequence of the continuous beam is adjusted.The finite element model is used to carry out the grid static test of the concrete continuous beam.The experimental results show that this method can effectively improve the strength and construction efficiency of concrete continuous beams by adjusting the closure sequence of concrete continuous beams by hanging basket method.Improve construction quality.
