The Consolidation Degree Analysis Of Using Load Pre-pressure Drainage Consolidation Method to Consolidate Soft-soil Foundation

Abstract:

This paper calculates the consolidation degree by using the theory of three-dimensional consolidation and taking account of the monitoring test results of pore pressure dissipation. It is proved that they are practical by contrasting with each other. In addition, according to equation of calculating consolidation degree, it can calculate ultimate settlement and predict the time when settlement is stable by contrary. It has important leading purpose to put forward the time of unloading.

Key words:load pre-pressure; drainage consolidation method; soft-soil foundation; consolidation degree; settlement
