Abstract
The deformation mechanism of engineered municipal construction waste (EMCW) is complicated and different from that of the traditional soil. A series of field tests and field measurements were performed on the piled mountain project to investigate the deformation characteristics of EMCW during the construction waste accumulation. Experimental studies revealed that EMCW was defined as a kind of heterogeneous soil with well-graded soil. The coefficients of uniformity were all greater than 10, while the coefficients of curvature were between 1 and 3. The permeability had approximately the same performance as the sandy gravel did. The field test results showed EMCW had the characteristics of small deformation and the time effect of loading. The p–s curves indicated that the bearing capacity of construction waste improved after 1 year’s filling. These phenomena were mostly caused by the complexity, diversity, and inhomogeneity of EMCW. According to the proposed control standards of settlement and lateral deformation, as a method of foundation treatment, EMCW was an effective way to build a large piled mountain on soft soil foundation.
