Abstract To study the damage law of rock under dynamic and static superimposed loads，a rock mechanics experimental system with multi strain rate dynamic and static superposition was developed. The experimental system includes assembly reaction unit，dynamic and static superposition unit，creep loading unit and intelligent control unit. The four units have the characteristics of assembly with high rigidity，multi strain rate dynamic and static load superposition and simulation of elastic strain energy release，automatic balance creep loading，multi-element information acquisition and automatic high-frequency capture of sudden change information，respectively. Finally，various types of dynamic and static loads with different strain rates，such as creep(＜10－4 s－1) and static load (10－4–10－2 s－1)，static load and pulse load(10－2–100 s－1)，static load and impact load(100–102 s－1)，static load and cyclic impact load，can be applied on a single rock surface. Using the experimental system，the marble damage and failure experiments under the dynamic and static superposition were carried out，and the damage evolution law quantitatively characterized by the peak strength and cumulative residual strain. The experimental results showed that the creep，static load + pulse，static load + impact have obvious damage effects on rocks，the damage effects from strong to weak are: static load + pulse，static load + impact，creep. At the moment of dynamic and static superposition，the strain increases abruptly，when the dynamic load is significantly smaller than the static load，the dynamic load mainly produces elastic strain. When the dynamic load is the same，the damage increases rapidly with the static load increasing；when the static load is the same，the damage decreases with the increase of the dynamic load strain rate，which has a significant strain rate effect. In the process of static load + cyclic impact，the specimen damage presents an S-shaped evolution trend of “rapid growth→gentle development→rapid rise”.

Key words： rock mechanics multi strain rate dynamic and static superposition experimental system development dynamic disasters
