Abstract

Abstract

Based on a group of one-dimensional consolidation test of Fuzhou soft soil in undisturbed and remolded state the structural characteristics of soft soil is examined. Secondary consolidation properties of soft soil has been researched based on a series of one-dimensional secondary consolidation test for undisturbed samples and overload pre-pressure soft soil. The results show that the soft soil of Fuzhou is with structural, for that undisturbed soil and the remolded soil consolidation curve is obviously different; the separation of primary consolidation and secondary consolidation and the secondary consolidation ratio Cα of undisturbed soil are related to structural strength. These two characteristics are depends on preconsolidation pressure pp in structural damaged soil after preloaded.
