Abstract:Inclination-rectifying construction of drawing out soil in drilling hole is simple, without vibration, and without damage to the original structure, which can effectively reduce the risk of structural instability of the inclined ancient masonry pagoda in loess area. Combining with the engineering practice of inclination-rectifying of drawing out soil in drilling hole for Wanshou Temple ancient masonry pagoda in Guanzhong loess area of Shaanxi province, the main problems of drawing out soil in drilling hole technology were discussed, such as the applicable conditions of the technique, investigation method for the inclination cause and mechanism of pagoda body, analysis of construction mechanical behavior of foundation-pagoda body synergy in the process of inclination-rectifying, principles and methods of pagoda body structure stability protection, arrangement principle of working pit and holes main parameters and influencing factors of pagoda body back inclination control etc. The results indicate that the overall stability of the pagoda should be considered first when choosing foundation soil for drilling holes, the depth of the holes and the inclination angle of the holes. The diameter of holes，rows of the holes, drawing out the volume of soil etc., should be designed for the purpose of controlling the rate and direction of inclination-rectifying.

Keywords:ancient masonry pagoda;inclination-rectifying;drawing out soil in drilling hole;construction mechanical behavior;overall stability
