文章以内蒙古老集高速公路部分开裂圆管涵为工程背景,通过理论分析并运用大型通用有限元计算软件ANSYS8.0,对可能导致圆管涵开裂的各种原因进行了分析,结果表明,施工方法不当和混凝土收缩是引起圆管涵开裂的主要原因。
Based on the engineering background of some cracked round tubular culverts in Laoji Expressway in Inner Mongolia, this paper analyzes various reasons that may lead to cracking of circular pipe culverts by theoretical analysis and application of large-scale finite element software ANSYS8.0. The results show that construction Improper method and shrinkage of concrete are the main reasons for cracking of circular pipe culvert.
