The cliff body has been severely damaged by diverse wind erosion and secondary relaxed fissures of cliff bodies in the Jiaohe Ruins. It is important to study the influence of diverse wind erosion and secondary relaxed fissures on cliff bodies and damaged pattern under both of them. The finite element software ANSYS is used to simulate cliff body damage under diverse wind erosion and secondary relaxed fissures. In order to verify the result of finite element software simulation

the basal contact friction test is carried out to simulate the cliff body damage process. The result of finite element software simulation illuminates that the maximum displacement of the cliff body is 487.326 mm

the maximum plastic strain is at the root of the relaxed fissure

and the cliff body is fracturing and toppling. The result of the basal contact friction test shows that the open width of the fissure is 20 mm after 2.7 h

and then the soil body is falling. The fracturing-toppling progress is that the bottom of silty clay layer incised by secondary relaxed fissure is empty; the root of relaxed fissure is pulled apart; the incised soil body is inclined deformation; and then the root would appear tensile failure and the soil body would topple and fall. For the impacts of diverse wind erosion and secondary relaxed fissures on damage of cliff bodies

the reinforcement program of cliff bodies is brought forward.
