The Environmental Protection Methods for Vacuum Preloading Project

Vacuum preloading is one of the effective technologies for consolidating soft foundation. The consolidation mechanism of vacuum preloading is explained. Meanwhile, the computing methods of vacuum preloading are classified, the advantages and disadvantages of the axial symmetry consolidation theory, the half analysis theory of horizontal movement and the three dimension value solution, are evaluated. Especially the key environmental problems of the vacuum preloading have been further investigated. In addition, on the basis of analyzing the characteristics of vacuum preloading, application prospect of vacuum preloading is predicated. Finally the environmental protection methods are provided.
