RESEARCH ON KEY INDEX OF DEVIATION RECTIFICATION TECHNOLOGY FOR MASONRY PAGODA BY HOLES-DRILLED AND SOFTEN

摘要：

In order to study the key point of the technology of holes-drilled and soften,which is a deviated rectification technology in collapsible loess areas. By which the control of the process of deviated rectification can be achieved. In light of deformation characters of collapsible loess,the soften of loess after water injected be modified by reduction of deformation model and index of strength,and the increase of water injected be modified by that of volumes of soften soil,the whole process of deviated rectification of Jingguang Pagoda is numerical simulated by Finite Element Method(FEM). The results of calculation indicate that the stresses in bottom of the tower are higher and that should be monitored. Sometimes it can be strengthened if necessary. There are two stages during the process of deviation rectification for the pagoda,and the large scale and fast deviation rectified is appeared in the second stage so that the structure of the pagoda is destructive easily. So the structure of the pagoda should be monitored to ensure the safety of construction and the effect of deviation rectification. As a result,the key index of the technology of hole-drilled and soften is given.
