The results show that the creepprocess is the gradual structural damage and structure trends to be stable.
研究结果表明：软土蠕变过程是结构逐渐破损，结构趋向稳定的过程；

The variation law of saturated broken mudstone porosity during creepprocess is studied by using the self-developed multiphase coupling creep test device.
利用自制的破碎岩体多相耦合蠕变试验装置，研究饱和破碎泥岩蠕变过程中孔隙的变化规律。

The main structure changes in the creepprocess were fiber rearrangement, the oxidation of the C-rich interfacial layer and crystal growth within the matrix.
