Research on Deformation Control of Anchor Bolt Supporting Red Clay Deep Foundation Pit

Abstract:

In order to study the deformation characteristics of red clay deep foundation pit, the horizontal displacement of lateral wall and the subsidence of surrounding surface were analysed in the step-by-step excavation of red clay deep foundation pit in the construction process. Using finite element software and D-P model, the numerical simulation of a deep foundation project was done. On this basis of differentiated models, the deformation characteristics of different support schemes were further analysed. This study indicates that the spacing of anchor bolt affects the deformation most, followed by the length of anchor bolt and pre-stress. The result shows that selecting a rational scheme for design and construction according to special conditions is important, which can not only guarantee the foundation pit safety, but also save the engineering cost．
