The combined support of pile (wall)-bracing-anchor, a new supporting type, has been developed based on pile (wall)-bracing and pile (wall)-anchor and has more advantages. It can effectively control the surrounding deformations of excavations and facilitate the excavation and construction of underground structures. The application of the new supporting type in three projects has achieved good results. Based on the studies on the deformation compatibility of the combined support of pile (wall)-bracing-anchor, increasing the stiffness and the ability to deformation control of anchors is the key technique. It's believed that deep displacements of the new supporting type and the pile (wall)-bracing support can achieve the similar level by taking some measures through analyzing the deformation characters of these two types during three stages of foundation construction-use-bracing substitution, and five technical measures of enhancing the ability to control deep displacement are provided.
