Abstract：
The supporting and protection forms, including bored pile and prestressed anchor bar, are adopted to the 3-layer basement of Financial Services District engineering in Wuxi New District. Influence factors on deep foundation pit deformation have been systematically studied. Focused on the characteristic of this deep foundation pit that is rectangle, long side effects have been analyzed, and its affect models have been initially proposed. Effective measures such as lengthening prestressed anchor bars and temporary setting mound supports have been enforced to fade long side effects. Some technique and management control measures have been applied on prestressed anchor bar construction, triaxial mixed pile construction and pit monitoring to ensure safety.
