In order to scientifically preserve the excavated four ancient well heritages in Nanjing Dabaoen Temple.Firstly,the actual structural performance of the ancient wells was analyzed with ANSYS.The structural safety problems under the actual environmental influence and load combinations were found out.Then adaptive conservation design was presented based on the conservation rules and the results of theoretical analysis.The structural performance of the four ancient wells strengthened with the adaptive conservation method was analyzed by ANSYS,and the validity and reliability of this adaptive conservation method were also verified.Finally,the relationship of the structural performance and the main influence parameters were also studied and presented.
