摘要
基于软土结构性分析 ,提出了固结系数分段模型 ,同时给出了考虑土结构性影响的瞬时加载砂井地基固结度的计算方法 ,使计算分析趋于合理。算例表明 ,土结构性对砂井地基固结性状影响明显。
Based on the analysis of soft soil structure characteristics, a subsection model of consolidation coefficient is presented, in the meantime the formula of the consolidation degree of sand drains ground is derived under the condition of instant loading, where soil structure characteristics is taken into the formula account. As a result of considering soil structure characteristics, the result becomes more reasonable. The example suggests that the effect of soil structure characteristics on the consolidation of sand drains ground is notable.
