In view of the cracking of the fine stone concrete spray layer, it loses its function, especially the steel mesh in the spray layer loses its protection and corrodes. To this end, according to the monitoring data of about 10 years of cutting rocky high slopes with a depth of about 200 m in Zhongyuntai Mountain in Lianyungang, the analysis of the cracking of the fine stone concrete sprayed layer was carried out. The axial force of the steel mesh on the slope is positively correlated with the temperature. According to the principle of strain coordination, the fine-stone concrete has the problem of pulling cracks along the slope, which is one of the reasons for the cracking of the fine-stone concrete on the slope. The position of horizontal displacement leads to the phenomenon that the sprayed layer of the fine stone concrete on the slope surface is lifted, which is another reason for the damage of the fine stone concrete on the slope surface.
