含建筑垃圾土是一种包含有建筑垃圾的地基土体，其主要成分为土、碎石、碎砖、玻璃以及少量塑料，这些建筑垃圾成分使得该土体具有新的物理力学性质.经过一系列的物理力学试验研究，发现含建筑垃圾土属于非均质级配良好土，具有较高的抗剪强度指标，这主要是由其中的碎石等大颗粒在荷载作用下的咬合力所起到的抗剪作用；另一方面，由于沉积年代较短，浅层含建筑垃圾土结构松散，固结试验结果表明，该土体具有较高的压缩性.

The physical and mechanical behavior of soil with construction waste is different from those of ordinary soils. Experimental studies on these properties have been carried out. Apart from soil, soil with construction waste contains gravel, cracked bricks, glass, plastic, etc. Based on the experiments, soil with construction waste is defined as a kind of loose and incoherent soil with high bearing capacity and shear strength. The shear strength parameters c and φ are heightened compared to the ordinary soil. Consolidation test results show that this kind of soil has high compressibility.
