Abstract: The compression coefficient in settlement calculation for vacuum preloading is based on the oedometer test, but the stress state in ground for vacuum preloading is different from oedometer test, the results of settlement calculation is unreasonable used parameter from oedometer test. The theoretic analyses in elastic condition, compression test by trixail apparatus with automatic controlled stress that can simulate the stress path in vacuum preloading, and field monitoring in project of vacuum preloading are presented. The ratio of isotropic to one dimensional consolidation in elastic condition under same load, compression coefficient from trixial test and oedometer test are discussed. Settlement results of field monitor and calculation show above consideration is reasonable.

Key words: vacuum preloading, settlement calculation, compression coefficient, stress state
