A simplified method for calculating pile cap of pile-raft or pile-box foundation in high-rise buildings, named Spring Constant Method, is developed, and the calculation formula for the spring constant based on settlement computation is presented. It is proved by the sample that the calculation result of the presented simplified method is rational, and the calculation process is much simplified. The presented method is practical for the foundation design of high-rise building.
Keywords: high-rise building; pile cap; spring constant
