温度影响下透明土-混凝土接触面摩擦力学特性试验研究
Experimental on interface mechanical of transparent sand concrete influenced by temperature
摘要
Abstract
Based on transparent sand material and digital image processing technology,the visualization of model test method for geotechnical engineering was gradually applied.However,the researches focused on the mechani-cal properties of interface between transparent sand and concrete structures (such as,pile foundation)were rela-tively little.Besides,the researches focused on the transparent sand concrete pile interface mechanical properties influenced by temperature effect was relatively less.Based on laboratory tests,two transparent sand materials (fused silica and baked quartz),which are commonly used at home and abroad,were chosen for studies.The interface mechanical properties between these two transparent sand and concrete influenced by temperature was taken out.For comparison,the interface mechanical properties between sand and concrete influenced by temper-ature was also carried out.The results show that the interface mechanical properties between these two transpar-ent materials and concrete material are similar with those between sand material and concrete.It indicates that these two types of transparent sand materials can be used in the simulation of natural sand -concrete interface characteristics.It also shows that the values of interface mechanical properties are influenced by temperature effect un-obviously.关键词
