摘要/Abstract

摘要： 阐述了天津市深层粘性土对地面沉降的影响，分析了深层粘性土的固结规律。通过研究孔隙结构和孔隙水运移特征，探讨了坚硬粘性土的固结变形机理。选取由固结旋回法得到的固结参数对深层粘性土引起的地面沉降量进行了计算，获得了较好的预测精度。

关键词: 深层粘性土, 地面沉降, 固结规律, 固结系数

Abstract: The impact of deeplying cohesive soil on subsidence in Tianjin is presented in this paper. Based on the analysis of the consolidation law of deeplying cohesive soil, the pore configuration, and the movement of pore water, the mechanism of the consolidation of hard cohesive soil is discussed. Finally, the consolidation parameters, resulting from consolidation cycles, are applied in the calculation of settling volume and the degree of forecast accuracy is satisfactory.

Key words: deeplying cohesive soil, land subsidence, consolidation law, consolidation parameter
