Deformation characteristics and stability evaluation for 26-D section of cliff in Jiaohe ruins after reinforcement

摘要

Cliff of Jiaohe ruins has both geological engineering property of ordinary soil slope and property of heritage site,which results in the particularity of methods and effect evaluation for reinforcement.By means of engineering geology and horizontal deformation survey of four sections,the paper finds out the deformation characteristics of after-reinforcement cliff.With the comparison of deformation characteristics between pre-reinforcement and after-reinforcement,in-site survey data indicates cliff after reinforcement gradually readjusts its stress and strain.It can be concluded that with excellent reinforcement method cliff is apt to stability from the gradual depression of quantity and extent of deformation.
