摘要: 土与结构接触面直剪试验是研究接触面力学特性的有效途径,在常规直剪仪的基础上改进了混凝土制备方法,即分别制作混凝土垫块和面块,预埋吊装钢筋,并以三峡库区碎石土为研究对象,开展了一系列不同法向应力和不同初始含水率条件下的碎石土与混凝土室内大型直剪试验,得到了其接触面力学特性的变化规律,试验结果表明该试验方法方便可行,可为土与结构相互作用大型直剪试验研究提供一定的参考。

Abstract: The direct shear testing between the soil and contact structure interface is one of the efficient way of characterizing the contact properties of various materials. The interface testing device was modified from the conventional large scale direct shear testing equipment by separately preparing the concrete blocks at the bottom and the face blocks made with other soil material sample at the top. The interface direct shear tests were performed with various gravelly soils in Three Gorges area under different normal pressures and different moisture contents. The test results are satisfactory.
