THE INFLUNENCE OF DEEP CLEARANCE ON THE SETTLEMENT OF ADJACENT STRUCTURES

In the reconstruction tall-rotating process of the old urban area, it is often necessary to clear the natural or artificial structures that affect the proposed project. How to protect key structures in the process of obstacle clearance has become the focus of attention of structural engineers. Based on the cases of pile pulling construction in soft soil layer of Shanghai with tall-skave drill, the paper discussed the influence of the construction process and accidents on the settlement of the adjacent structures by analyzing the measured data. The analysis results showed that it was necessary to arrange the pile pulling construction process reasonably and deal with the accidents occurred in time in order to control the settlement of adjacent structures.
