Abstract：The detachment is one of the most critical diseases of ancient architecture murals at Tibet，and the area of detachment murals make up more than seventy-five percent of the total area of diseases murals. Based on working out measurable evaluation for the phenomenon of detachment murals and its repairing effect，the distribution of detachment murals were detected by ground-penetrating radar at the Potala palace，furthermore the reflection characters of electromagnetic wave were analyzed in detachment murals. For the detachment murals，PS materials of some moduli and concentrations were grouted into the detachment area. During one year for maintenance，the distribution of the detachment murals was detected by ground-penetrating radar again. It shows that the reflection signals of electromagnetic wave are strong in the stone-wall before grouting the detachment area，but after grouting the detachment area，it can not be detected between layers due to the detachment area felted for whole by PS material. It indicates that the grouting technology of PS material can effectively repair the detachment murals，and ground-penetrating radar can accurately improve the status of detachment and its repairing effect.
