The research showed that in –2025, the total excavated soils and construction sludge production in Wenzhou would reach 107.5 × 10 6 and 81.7 × 10 6 m
A weak interlayer zone (WIZ) is a poor rock mass system with loose structure, weak mechanical properties, variable thickness, random distribution, strong

1. Introduction. The utilisation of excavated rock and soil has gained worldwide significance in a circular economy based on the principle “Reduce, ReUse and Recycle” (Esa et al., ; Geissdoerfer et al., ; Ghisellini et al., ; Huang et al., ; Korhonen et al., ).More than 200 international tunnels longer than 3000 m are
stability of excavated rock slopes in the field and make potential adjustments to slope angles as rock mass conditions become visible during construction (Barton and Bar, ). The Qslope method is intended for use in reinforcementfree rock slopes and it is based on the results from more than 500 case
The research showed that in –2025, the total excavated soils and construction sludge production in Wenzhou would reach 107.5 × 10 6 and 81.7 × 10 6 m 3, respectively. Furthermore, the excavated soil was classified into the miscellaneous fill, crust clay, muddy clay and mud with silty sand.
Stability of excavated or natural slopes in soils and rock masses is frequently influenced and controlled by the existence of joints and weaker zones or layers. The properties of rocks and soils used in the previous research of slopes had commonly been modelled deterministically with a perfect spatial
Arsenic release from excavated rock with steel slag in dialysis test. The amounts of arsenic released from R1 with and without the steel slag were 0.47 and 1.40 mg kg −1, respectively (Fig. 1), and the pH values were 8.0 and 10.4, respectively.In geological environments such as soil, sediment, and rock, arsenic is readily mobilizable under
using excavated soil and rock in other projects was considered to be able to r esult in a. cost saving of 30% and an emissions reduction of around 100 tons of CO. 2. In the final.
In the process of tunnel excavation, the cutter wear rate is accelerated when the tunnel boring machine (TBM) passes through the rock stratum and the cutter is commonly replaced frequently during the excavation. In the replacement stage, the stability of the excavation surface is crucial to the operation of the project. In this study,

At the current construction section from Pfons to Brenner, that started in autumn , the recycling of the excavated rock plays an important role in providing rock aggregate for the construction site. There, the reuse of rock material mostly excavated during continuous tunnel driving at a variable geology is a demanding task with a

In the replacement stage, the stability of the excavation surface is crucial to the operation of the project. In this study,
In this study, the leaching of chemicals from an excavated shale rock containing geogenic As was assessed using a shaking and nonshaking batch test. In those experiments, different temperatures up to 40 ºC and contact times ranging from 6–360 h were employed. Overall, it was found out that more As was leached with elevated
