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.
