项目摘要
The potential usage of magnetorheological fluids (MRFs) for temporary in-situsolidification of coarse-grained soils is being investigated. Should magnetorheologicalmaterials be successfully introduced into the pore space of a soil and solidified byapplication of a magnetic field, they could significantly improve our ability to samplesaturated or dry cohesionless soils with minimum disturbance. The cost savings overpore fluid freezing could be very significant. Other potential future applications of MRFsin geotechnical engineering may include: stabilization of soil for excavation andtunneling, control of seepage and contaminant migration, liquefaction hazard reduction,control of machine vibrations, soil surcharging to accelerate pre-construction settlementand others. The present exploratory laboratory program will include tests for hydraulicconductivity, stiffness, strength, volume change susceptibility due to vibration, andstability of open cuts in MRF-stabilized soils.
磁流变液(MRFs)用于粗粒土的临时原位固化的潜在用途正在研究中。 如果磁流变材料被成功地引入到土壤的孔隙空间中,并通过施加磁场固化,它们可以显着提高我们在最小干扰下对饱和或干燥的无粘性土壤进行取样的能力。 孔隙流体冷冻的成本节约可能是非常显著的。 MRFs在岩土工程中的其他潜在应用包括:稳定开挖和隧道的土壤,控制渗流和污染物迁移,减少液化危险,控制机器振动,土壤超载以加速施工前沉降等。 目前的探索性实验室计划将包括水力传导性、刚度、强度、振动引起的体积变化敏感性以及MRF稳定土壤中明挖的稳定性试验。
