中文摘要:
      结合跨那苏河(60+104+60)m连续梁桥0号块托架设计方案,根据MIDAS有限元软件分析结果判断结构强度和刚度是否满足要求,验算结构最不利位置的强度和稳定性。经验算托架结构能满足设计和一次性浇筑的施工安全稳定要求,结构构造简单可靠,施工简便,节约了成本,提高了工作效率。
英文摘要:
      With the design scheme for the bracket of Block 0 of the continuous girder bridge (60+104+ 60m) spanning the Nasu River as a practical example, whether the structural strength and stability are up to the requirement is judged by the result of the MIDAS finite element software analysis in the present paper, with the strength and stability of the most unfavorable position of the structure checked. Through the checking calculation, it is found that the bracket structure can meet the requirements of the design and the construction of the one time pouring in both security and stability. The bracket is simple but reliable in structural composition, simple and convenient in construction, and helps save cost and improve work efficiency.
