Energy transfer and influencing factors in soil during compaction. | LitMetric

Energy transfer and influencing factors in soil during compaction.

AI Article Synopsis

  • Large-area excavation and filling engineering in China is growing rapidly, making the quality of fill engineering crucial for building stability.
  • The study investigates the compaction characteristics of two layers of loess fill soil using a custom test system, focusing on how different compaction energies affect soil bottom pressure.
  • Results indicate that the compaction curve can effectively represent soil pressure changes, showing that increased soil density raises bottom pressure to a peak, and reveals an exponential relationship between energy consumption ratio and soil layers, aiding in understanding soil stability during compaction.

Article Abstract

In China, large-area excavation and filling engineering has increased rapidly with the expansion of construction land. The quality of filling engineering is the most important guarantee for the stability of building structures. Among all research on fill soil, the compaction characteristics are significant for indicating the strength and stability of filling engineering. In this paper, two layers of loess fill soil were compacted by a self-manufactured test system with three different compaction energies. Based on the variation in the soil bottom pressure obtained in the tests, the influence of the compaction parameters on the soil bottom pressure was investigated. The results show that the compaction curve can be used instead of the curve of the change in soil bottom pressure with water content; as the soil density increases, the soil bottom pressure increases to the maximum. The relation of the energy consumption ratio of the soil bottom (σ/σz) and the number of soil layers is exponential and reveals the stability of the soil skeleton formed during compaction. This paper describes the compaction characteristics of loess fill soil from the perspective of energy transfer, and the conclusions provide a theoretical basis for soil filling engineering.
