The combined support is usually used in the region of Dalian due to its complex ground structure. In one project, calculations, support designs and observations of the construction results have been carried out for foundation pit stability under different conditions, and it is proved that the combination of the hand-dug pile with the stiffness pile, the anchor cable with anchor bolt, and the woven net with sprayed concrete, provides better support for the foundation pit in complex ground, and also a successful field case in support of deep foundation in Dalian.
