- Abstract:
- This paper introduces the main types of diseases such as wind erosion,rain erosion,erosion,fissures and collapse in the Jiaohe Ancient City,summarizes its existing reinforcement methods,and conducts pulsation tests on typical sites.The results show that:①The natural frequency of the earth ruins is mainly between 1.72～6.03 Hz,and the damping ratio is mainly between 0.027～0.043,which is in line with the actual situation.②The natural frequency of the wall is larger than that of the pier of the tower,and it is greatly affected by the earthquake.Weak walls such as residential walls and Buddhist temple walls in Jiaohe Ancient City should be monitored and protected intensively.③The ground pulsation is transmitted from the bottom to the top,and its speed has obvious amplification effect,and the magnification is about 1.5～3 times.
