本文重点分析研究了与地面沉降密切相关的四个微观因素──压缩层的粘粒含量（及砂粒含量）、矿物成份、固结系数的微小变化、砂性土含水层微量压缩．
In this paper, four microscopic factors closely related to land subsidence are analyzed and studied: the clay content (and the sand content), the slight change of the mineral composition and the consolidation coefficient of the compressive layer, and the micro-compression of the sand soil aquifer.
