福州地区结构性软土次固结试验研究
摘要:为研究福州地区浅层软土的结构性特征,特进行了一组原状土和相应的重塑土的一维固结试验。通过原状土和预压后软土的一维次固结试验,探讨了软土的次固结特性。试验结果表明,原状土和重塑土的固结曲线明显不同,说明福州地区浅层软土具有结构性;原状土主次固结的划分以及次固结系数Cα与结构强度有关,经预压结构破坏以后土样的主次固结分界及次固结系数Cα主要受预压荷载Pp影响。
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.
