cantilever retaining structure caused the large lateral deformation in soft soil region. Improvement of soil is an effective measure to decrease the lateral deformation. Based on elastic foundation beam theory
a finite element model of foundation pit is founded. The effects of soil improvement on lateral deformation and inner force of cantilever retaining structure are studied. The results show that the lateral deformation reduces with the deceases of depth and degree of improvement of soil. There are critical depth and degree in improvement of soil. The change of inner force caused by depth and degree of improvement is small. To save the engineering cost and guarantee the pit safety
it is important to reasonably decide the depth and degree of improvement of soil.
