本文借助大型有限元分析软件ABAQUS对混凝土方形截面柱进行轴心受压仿真模拟，观察未加固方柱和加固后的方柱极限承载力变化情况和破坏形态，分析比较加固后的效果，发现加固后的方柱极限承载力明显高于未加固方柱，并随着加固层数的增加，方柱的极限承载力也明显提高，但提高幅度先大后小，最后趋于固定值。从加固结果可知，加固三层时方柱极限承载力提高幅度最大，此时的玄武岩纤维布利用率最高。

The axial compression square concrete columns is simulatied with the help of the large-scale finite ele-ment analysis software ABAQUS, observe the bearing capacity and failure patterns of square column and the column reinforcement, compare the effect after reinforcement column. The reinforcement of column ultimate bearing capacity was significantly higher than that without the strengthening of concrete square column, and with the increase of rein-forcement layers, and significantly improve the ultimate bearing capacity of square column, first big small, finally tends to a fixed value. From the results of three layers of reinforcement, reinforcement of ultimate bearing capacity of square column increased most, basalt fiber cloth at the highest utilization rate.
