| 摘 要： | 以研究徐淮矿区深部土体工程地质、水地质基本性质为基础，首次从吸附结合水含量及其性质方面，探讨了该区深部土体失不变形机理与同有一般认识的不同，得到该区内深部底含失水时粘土层不压缩、砂克层压缩的结论，对认识该区内井筒破裂、地面沉降等环境地质问题具有意义。

| Abstract: | On the basis of the engineering hydrogeological properties of the deep soil mass in Xuhuai Mine Area, the mechanism of deformation due to loss of water is discussed in terms of the content of adsorbed hydration water and its characteristics.A conclusion is drawn,when the bottom aquifer losing water,the sand gravel soil of the bottom aquifer,not the clay soil,is compressed,which is different to common understanding.This is of theoretical significance to recognition of some environmental problems in Xuhuai Mine Area,such as shaft lining rupture,surface subsidence,etc. |
