| 摘 要： | 粘土矿物在地面沉降中的作用、粘土矿物的脱水作用对地面沉降的影响等日益成为评价和防治地质、工程、水文、环境等问题的关键,也一直是相关领域的研究难题而逐渐引起高度重视。本文回顾了蒙脱石层间水性质、层间水化膨胀和脱水收缩的影响因素,提出蒙脱石层间的固溶体特征,在总结蒙脱石脱水作用与地面沉降关系研究成果的基础上,提出了用蒙脱石脱水作用研究地面沉降的思路。最后讨论了用蒙脱石的脱水作用研究地面滞后沉降及沉降趋势预测的可能性。 |
| 关 键 词： | 蒙脱石 层间 固溶体 层间水 脱水作用 地面沉降 |

| Abstract: | The function of clay minerals and the effect of clay mineral dehydration on land subsidence have become an increasingly important key point in the evaluation and solution of many problems in such aspects as geology,engineering geology,hydrogeology,environmental geology,and hence aroused more and more attention in geologists. This paper describes characteristics of montmorillonite interlayer water and factors affecting the swelling with hydration and the contraction with dehydration. The solid solution properties of the montmorillonite interlayer are pointed out. Based on the achievements made in investigating the relationship between montmorillonite dehydration and land subsidence,this paper puts forward the train of thought for further study of the secondary land subsidence in the light of montmorillonite dehydration. The possibilities of using the montmorillonite dehydration to the study of delayed land subsidence and the prediction of land subsidence are also discussed in this paper. |
| Keywords: | montmorillonite interlayer solid solution interlayer water dehydration land subsidence |
