Abstract:Based on the largest earthen architecture conservation engineering,Jiaohe ruins rescuing conservation engineering,and the particularity of the cliffs,Nanrui dam automatic monitoring instrument is applied to survey the deformation of cliffs during anchoring and grouting. Analysis of the monitoring of the cliff proves grouting disturbs the cliffs more intensely than anchoring. The deformation characteristics of the cliffs before and after the conservation illustrate the successful conservation of anchoring and grouting. The conclusion provides the foundation for entire scientific conservation of Jiaohe ruins;furthermore,it gives the reference to the research on the anchoring and grouting of similar earthen architectures.
