粘土

In this paper,Laterite soil adjacent to some stake of the highway in Chenzhou, Hunan section from Xiamen to Chengdu was used to investigate the deformation characteristics and protection methods of the Laterite soil subgrade under the influence of environment factors.Properties like water-holding capacity,capillary rise, coupled heat-moisture transfer and wetting deformation of samples under different compactness were studied through a series of laboratory tests.In addition,by using meteorological data of two consecutive years in Chenzhou,coupled process of moisture transfer and subgrade deformation was stimulated under the impacts of groundwater and the atmosphere.Specific work done in this paper is as follows:(1) Samples under different compactness were subjected to a series of conventional laboratory tests,such as permeability,consolidation,contraction,shear test and etc.

Firstly, the different effect of rectorite modification for the mechanical property of E-51 system were compared; the effect of organic clay for the viscosity and Gel-time of pure E-51 epoxy resin were checked separately; the influence of organic clay for hardening process was studied with FTIR technology; And, the infection of organic rectorite content in matrix for the mechanical property thermal-wet tolerance property aging resistance property and medium endure property for the both of two system were studied relatively. The effect of organization for the inter-layer distance of clay was denoted by XRD technology; To probe into the thermodynamics status about reaction, we investigated the heat discharging of reaction system in the help of DSC. The impact and crooking of solidifying system was observed with the SEM to investigate the decentralization of organic clay, and, at the base of this ,we discuss the mechanism of clay toughing-buildup polymer matrix.

In greywacke, the content of clay mineral often higher than 15%, clay mineral come from former clay mineral in sediments and their transformation. Clay minerals show plasticity. Clay mineral can damage the pore content of reservoir through distorting and filling into pore easily. These reservoir show low pore content and low permeability.

杂砂岩中的粘土矿物主要是沉积原生粘土矿物和原生粘土矿物转化形成的新生粘土矿物，粘土矿物在储集层中主要表现为可塑性，容易压实变形并充填到孔隙当中损害储集层物性，储集层物性主要表现为低孔低渗。
