Abstract: Based on the fatigue damage tests of rock-soil materials, a new mathematic model of the fatigue damage of rock-soil material is proposed by using system analysis method and signal process technique and the parameter of fatigue damage is defined by means of bulk tests. The results show that damage parameter defined is susceptible and can trace effectively damage process of the samples. The damage process is divided into crack pullulating, crack expanding and crack high-speed expanding stage. Moreover, the relation curve between damage parameter and cycle times shows that the fatigue age of cement samples which has the same adding cement ratio and age is different. The damage process of the sandstones which have different components is not completely similar, even though their fatigue age is the same

Key words: rock-soil material, fatigue damage, system analysis, damage monitoring
