Effect of soil conditioning on the permeability of coarse-grained soil in mechanized tunnelling [PDF]
Heliyon, 2023 In coarse-grained soils, the reduction of soil permeability via conditioning can effectively prevent groundwater from entering the chamber, thus providing better tunnel face control and ultimately preventing excessive settlements of the surface.

Soil conditioning tests of clay for EPB tunnelling
Underground Space, 2022 Tunnelling with earth pressure balance – tunnel boring machine (EPB-TBM) in clayey soil requires a careful conditioning to reduce the effect of clogging and stickiness. In the last decade, many researches have been carried out to understand how to reduce

Volume Matters: Dilution of Soil Inoculum Reduces Positive Plant–Soil Feedback in Pinus radiata Seedlings [PDF]
PlantsSoil conditioning can generate persistent plant–soil feedbacks (PSF) that influence plant performance under subsequent growth conditions, yet the role of soil inoculum volume in mediating these effects remains poorly understood.

Genotype-Dependent Soil Legacy of Woodland Strawberry (Fragaria vesca L.) on Plant Growth and Herbivore Resistance [PDF]
PlantsPlant genotypes can vary in multiple functional traits due to adaptation to heterogenous environments. However, whether such variation can extrapolate to effects on soils and further on performance of subsequent plants, thus generating a genotypic ...

Soil conditioning for EPB shield tunnelling
KSCE Journal of Civil Engineering, 2014 The use of conditioning agents that change the mechanical and hydraulic behavior of a cohesionless soil into an impervious and plastic paste is the key point for the correct management of EPB (Earth Pressure Balance) shield tunneling. The design of soil conditioning sets and the choice of the best products to be used require special laboratory tests ...

Study on plastic flow of conditioned soil within pressure chamber of deeply buried EPB shields tunneling through sandy stratum [PDF]
Scientific ReportsFor earth pressure balance (EPB) shield tunneling, the stability of tunnel face is controlled by the excavation and discharge rates of soil within tunnel pressure chamber. To ensure continuous discharge of soil from pressure chamber, the soil is required

Characteristics of Seashore Saline Soils in Guangdong Province and Improvement Strategies
Guangdong nongye kexue, 2023 Seashore saline soil is a kind of soil formed after the sediments flowing into the sea with surface runoff or shallow sea sediments lifted up by wind and waves, flocculated and deposited in the intertidal zone under the action of tides and ocean currents,

Effect of Soil Conditioning on Soil Penetration Resistance and Traction Power Demand of Ploughing
Agriculture, 2021 Soil compaction and degradation due to improper tillage are problems involving significant natural and economic damages. On compacted soils, suitable cultivation can be implemented only with higher energy and traction force input.
