2013年2月1日 · The flow box test (FBT) offers the advantage of measuring viscosity (η) in both plastic and viscous liquid states using displacement data. Some researchers (Varnes, 1978, Cruden and Varnes, 1996, Hungr et al., 2001) believe that mudflows are closely related to Atterberg limits, the liquidity index (LI), and the flow velocity (v).

from publication: Phase concept for mudflow based on the influence of viscosity | The phase concept implies that the state of soil changes from plastic to viscous liquid as a function of water ...

2013年2月1日 · The flow box test (FBT) offers the advantage of measuring the viscosity (η) in both plastic and viscous liquid phases using displacement data. Since the phase concept indicates the changes in plastic and liquid states as functions of the water content (w), the viscosity (η) can be reliably calculated from the derived flow curves.

To describe the behavior of mudflow, a laboratory test was developed using the flow box test (FBT). The current paper aims to elucidate how the FBT result (i.e., displacement profile) is...

In this study, the affecting factors in the alpha and beta particles emitted from natural radioactive soil sample was simulated using the Monte Carlo FLUKA code. Materials and Methods: These factors include the thickness of the sample, source-detector air gap, Mylar thickness, and gas detector density.

2021年2月1日 · Falling Ball Testing (FBT) is a recommended method for testing resilient modulus of subgrade soil, which brings about a higher requirement for modulus test. This paper...

2024年4月10日 · Results indicate the potential of FBT in reducing fertilizer use by about 20%, methane gas emissions in paddy rice by approximately 20%, reducing pesticides and pharmaceuticals use, energy saving due to improved efficiencies in irrigation, seed germination, and higher stocking densities in fisheries.

2024年7月25日 · The Compaction and its testing by field density test (FDT) are very important and repetitive steps during earthwork phases of construction at a project. The Compaction of the soil usually increases the shear strength of this soil, …

2024年2月29日 · Chatting with my agronomist this morning and he was telling me how some FBT agreements, down in more arable areas, had clauses in them requiring the land to be soil tested at the beginning and end of the term with a full spectrum …

Grain yield increased significantly under FBT. Film-bottomed tillage, especially at optimized depths, enhances soil physical and chemical properties, improves nutrient availability, and increases the grain yield of dryland spring wheat. FBT provides a viable solution to enhance food security in arid areas with similar conditions. 中文翻译：
