%X 基于室内土工试验,针对目前国内外常用的2种透明土材料(熔融石英砂和烘烤石英砂)与混凝土材料之间接触面的摩擦力学特性开展研究,着重分析混凝土温度变化对透明土-混凝土材料接触面摩擦力学特性的影响规律;为了对比分析,开展相同情况下砂土-混凝土材料接触面摩擦力学特性室内试验。研究结果表明,熔融石英砂和烘烤石英砂两种透明土材料-混凝土材料接触面摩擦力学特性与砂土材料-混凝土材料接触面摩擦力学特性相似,说明该2种透明土材料可以较好地模拟天然砂土-混凝土材料接触面特性;温度因素对透明土材料-混凝土材料接触面摩擦力学特性有一定影响,但影响并不明显。<br>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 mechanical properties of interface between transparent sand and concrete structures (such as, pile foundation) were relatively 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 temperature was also carried out. The results show that the interface mechanical properties between these two transparent 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
