| 摘 要： | 由于蠕变试验费时长、耗资大，在实际操作中比较困难，长期以来制约着蠕变试验的发展。本文利用岩土分析软件FLAC3D建立试验模型，对室内蠕变试验进行模拟研究。采用同实际试验相同的试验状态、加载设计和时间设置，得到了同实际情况相似的蠕变曲线并进行了蠕变变形分析，进而延伸到常规三轴压缩的试验状态。

| Abstract: | Physical creep experiment needs long time-consuming, costs greatly, and operates more difficult. The development of experiment is more difficult. This paper establishes a numerical model using the rock soil analysis software FLAC3D, carries out simulation test for the indoor creep experiment. The numerical test adopts the test state, load design and time setting as same as those actual physical test. It can obtain the same creep curve of actual physical test. The simulated results can be used to analyze creep distortion. Moreover, the method has been extended to the test state of tri-axial compress creep test. It provides a new road for creep test research. |
