“…After testing the reinforcement, the vertical displacement of the embankment's daily variation was less than 5 mm and the cumulative displacement was less than 60 mm, within the allowable range. Ho et al [15] used high-pressure jet-grouting pile technology to strengthen soil in order to minimize disturbance to the surrounding ground during a basement excavation project, and the movement of the inner wall in the place where the jet-grouting pile was used was limited to 11.2 mm, when previously, it was 38.4 mm. Qiu et al [16] studied the settlement performance of a three-lane tunnel with a large cross-section in Gansu Province after the use of high-pressure jet-grouting piles.…”

There is a notable difference between garbage pile foundations and general site foundations; due to their uneven particles, complex structure, and diverse composition, there are relatively few cases that can be used for reference. In this study, with the aim of renovating a landfill in Shenzhen, bearing-layer reinforcements were introduced in the overlying road of a garbage heap dominated by construction waste. The bearing capacity of a single-pile composite foundation was studied through a core-pulling test of high-pressure jet-grouting piles, a static load test of the bearing capacity of the single-pile composite foundation, design estimation, and numerical analysis. The results show that the obtained eigenvalue of the design estimate was 267.8 kPa, and the eigenvalue of the field test was between 182.58 kPa and 196.89 kPa, meeting the design requirement of an eigenvalue of no less than 175 kPa. The bearing capacity of the composite foundation of the single jet-grouting pile was analyzed using the ABAQUS numerical simulation software; the characteristic value of the bearing capacity of the single-pile composite foundation was 186.01 kPa, and the variation trend of its settlement–load curve was the same as that of the field test results, which met the design requirements. High-pressure jet-grouting pile technology has achieved remarkable results in the reinforcement of foundations that are mainly composed of construction waste.
