2023年10月12日 This paper investigates the initial state of excavated soil and rock (ESR). These initial states include dry density, organic content, water content (W c), cement content (C c), liquid index (LI), dry or wet mixing method.Three ESRs collected from tunnelling projects and kaolin were used in this study to compare.
Characteristics of the immobilization process of arsenic depending
2021年11月15日 The arsenic-containing excavated rock/sediment that is reused for embankments and roadbed materials should not pose an environmental risk (Katsumi, 2015). An estimation of the amount of potentially harmful elements released from excavated rock/sediment is necessary for developing an appropriate design for the chemical immobilization technique.
Re-using excavated rock from underground tunneling activities
2024年7月1日 Excavated tunnel rock, being a by-product of tunnel engineering, can pose various issues such as altering the original surface environment, triggering geological disasters, and posing threats to the surrounding and downstream environments if not appropriately disposed or utilized [24].Meanwhile, managing the huge amount of tunnel rock excavations incurs
