试验旨在研究在较高轴压比条件下，高弹模PVA纤维对超高强混凝土短柱抗震延性的改善作用。
The primary objective is to study the effect of high-modulus PVA fibers on improving the seismic performance of super-high-strength concrete short columns with high axial pressure ratio.
试验发现，初始弹模与围压呈较好的线性关系。
The test results show that there is a linear relationship between confining pressures and initial tangent modulus.
并用压坯单重递减法试验证实，当将压模收缩比增加到1 2 2以上时，可以保证压坯内孔不出现裂纹。
The test of single compact weight decrease proved that when the shrinkage ratio of the compacting die is increased to over 1.22, there is no more crack initiated in the compact inner hole.
