Abstract: The formula for deep-mixing pile composite foundation on the code is bad with correlation of the geologic strata parameter (such as soil modulus on the end of pile foundation, pile foundation size, subsidiary stress etc). So, it is more difficult to accurately calculate modulus of grid composite foundation. Based on the interaction of grid and soil, a formula about compressive modulus of grid composite foundation is deduced. By comparing the field static load test results of engineering of high-rise building, it is proved that the formula is reasonable for calculating for grid foundation for high-rise buildings.

Key words: confining pressure about soil, grid, composite foundation, compressive modulus, formula
