Difficult Issue

Crack prevention of high-rise building foundation is an interesting and difficult issue to engineers. Reasons for the crack are analyzed first. Then, based on project cases, crack control methods of large volume concrete foundation are studied in terms of active part and passive part. Active part includes optimizing design of concrete, optimizing foundation design and improving confining condition. Passive part includes reducing temperature difference and increasing the fracture strength of concrete. Finally, optimum foundation design is emphasized for crack control of large volume concrete foundation.

Structural Solutions

The paper presents two structural solutions for the high-rise building pile foundation where stylobate and high-altitude parts are not separated by a contraction joint studying results. The main difference between these structural solutions is in the use of piles of different lengths: in the first version all piles have the same length (implemented in practice) and the second version (perspective) is use of different lengths of piles and their support various engineering-geological elements (EGE): the longer piles support by stronger EGE under the altitude part and the shorter piles support by weaker EGE under the stylobate part. In calculations of the adopted versions piles tests results and geodetic observations have been considered for the used calculation methods verification

Settlement Analysis

The development of raft foundation design guide (RFDG) used in the high-rise building was programmed based on the secondary development language of ANSYS, such as TCL/TK, APDL and UDIL. The RFDG program provides a friendly GUI, which can be used expediently for the numerical experiment. The settlement analysis of raft foundation in the case study was carried out by RFDG. At the same time, the main technique for the secondary development of ANSYS has also been discussed in this paper.
