摘要
对衡水沉降漏斗中心地层分层取样,进行不同压力等级下的高压固结试验,研究各压力等级下土的压缩固结特性,在试验基础上系统总结了衡水沉降区整个第四系不同埋深黏性土固结特点和规律,分析了黏性土固结特性与地面沉降之间的内在关系。
The stratified samplings from subsidence cone center in Hengshui were taken for compression consolidation tests in different pressure levels to analyze compression consolidation characters of the soil. On the basis of tests, the paper systematically summed up that consolidation features and rules of different depths layers throughout the Quaternary in Hengshui, and analyzed the inherent relationship between the consolidation characteristic of clay and land subsidence.
