| 摘 要： | 对本区地层结构及深层地下水开采现状的研究表明,土层应力效应特征是发生地面沉降的内因,超量无序开采深层地下水是其外因.鉴于目前实测数据缺乏,运用太沙基有效应力理论和一维固结理论,估算地面沉降量.发现最终地面沉降总量为534 mm.截至2010年研究区实际沉降量132.7 mm,沉降速度缓慢.最后,提出当前的控制对策以及进一步研究的方法与建议.

| Abstract: | The study of the stratigraphic structure and the deep groundwater exploitation in the zone show that soil stress effect is the internal cause of the subsidence while excessive and disorderly exploitation is their external factor.Terzaghi effective stress theory and one-dimensional consolidation theory are used to estimate its settlement and it is found that the actual settling velocity is slow.Finally,control measures and further research methods are advised. |
