| 摘 要： | 为了有效地防治新集矿区地面沉降,研究了该区第四系松散层的工程地质特征与地面沉降的关系:松散层的大部分力学参数在地表以下30m内变化不大,埋深大于30m后变化明显;粘性土的压缩性明显大于砂性土;粘土中伊利石含量高,排水条件好,压缩性好。将松散层划分为3个主要压缩层;建立了地面沉降计算模型,预测区内地面沉降为0.2832~0.8293m。

| Abstract: | In order to effectively control the land subsidence in Xinji Mining Area,the relationship between the engineering geological characteristics and land subsidence of Quaternary loose bed in this region is analyzed.Most of mechanical parameters of loose bed is less varied within 30m below the surface,but is obviously varied below the buried depth of 30m.The compressibility of clayey soil is larger obviously than that of sandy soil because the clay contains high content of illite,with better drainage condition and larger compressbility.The loose bed is divided into three main compressible layers,and the calculating model of land subsidence is estabished.It is predicted that the land subsidence ranges in 0283208293m in this region. |
