摘要

研究了怀俄明型膨润土(MX-80)在不同水化水平下的水力学响应及其与钢的界面抗剪性能。在全吸力控制条件下进行了恒正应力剪切试验。在膨润土样品的情况下，较高的吸力水平获得了更高的剪切阻力。膨润土/钢界面的剪切性能总体上低于膨润土的内部性能，且受水化水平的影响不显著。所有试样在剪切过程中均表现出压实响应。

Hydro-mechanichal characterisation of bentonite/steel interfaces

The hydromechanical response of a Wyoming-type bentonite (MX-80) and its interface with steel was studied in terms of shear resistance under different hydration levels. A series of shear tests under constant normal stress were performed in total suction controlled conditions. In the case of bentonite samples, higher shear resistance was obtained for higher levels of applied suction. The shear properties of the bentonite/steel interface were overall lower than the internal properties of the bentonite, and they were not affected in a significant way by the hydration level. All samples presented a compactive response during shearing.

期刊介绍： Applied Clay Science aims to be an international journal attracting high quality scientific papers on clays and clay minerals, including research papers, reviews, and technical notes. The journal covers typical subjects of Fundamental and Applied Clay Science such as: • Synthesis and purification • Structural, crystallographic and mineralogical properties of clays and clay minerals • Thermal properties of clays and clay minerals • Physico-chemical properties including i) surface and interface properties; ii) thermodynamic properties; iii) mechanical properties • Interaction with water, with polar and apolar molecules • Colloidal properties and rheology • Adsorption, Intercalation, Ionic exchange • Genesis and deposits of clay minerals • Geology and geochemistry of clays • Modification of clays and clay minerals properties by thermal and physical treatments • Modification by chemical treatments with organic and inorganic molecules(organoclays, pillared clays) • Modification by biological microorganisms. etc...
