This study presents a series results of plate loading tests on a clay with various construction and demolition (CD) materials conducted in a large-scale model box and a numerical verification on the use of these material mixtures. The tests have been applied to the clay with three different types of CD materials (concrete, asphalt, and brick) prepared in a reinforced concrete circular box with a diameter of 2.0 m and a depth of 1.5 m. The CD materials were added to the clay with a mix ratio of 10% by dry weight and then compacted at optimum water content (w_opt) and corresponding maximum dry density (γ_drymax). The testing results have indicated that the CD materials increased the ultimate bearing capacity of the clay with a range of 50–75%. Furthermore, a remarkable correlation between the results of plate loading tests and numerical simulations made by a commercial finite element software (Plaxis 2D) was observed for all mixtures tested.

这项研究提出了在大型模型箱中对具有各种拆建（CD）材料的粘土进行板载荷测试的一系列结果，并对这些材料混合物的使用进行了数值验证。该测试已应用于由三种不同类型的CD材料（混凝土，沥青和砖块）制成的粘土，这些材料在直径为2.0 m，深度为1.5 m的钢筋混凝土圆形箱中制备。的CD材料添加到具有按干重计的10％的混合比的粘土，然后在最佳含水量压实（瓦特_选择）和相应的最大干密度（γ _DRYMAX）。测试结果表明，CD材料将粘土的极限承载力提高了50-75％。此外，对于所有测试的混合物，都观察到了板载荷测试结果与商业有限元软件（Plaxis 2D）进行的数值模拟之间的显着相关性。
