... carrier. Hence, this study will investigate the heat transfer enhancement of the energy pile contributed by a nanofluid. The analytical model of a spiral coil energy pile with seepage and the correlations of thermophysical properties of the nanofluid were employed. The heat transfer capacity, wall...

... Abstract When the artificial ground freezing (AGF) method is used to construct underground structures in the coastal composite strata, the differences between characteristics of soft clay and silty sand under seepage often increase the risk of freezing construction and the difficulty...

Different seepage effects on water curtain holes under different spacing are calculated and analyzed using a numerical analysis method. The optimal water curtain hole layout is finally...

...-term operation, and its impact on the ground temperature will take about 30 years to recover. In addition, many scholars have found that the seepage of groundwater can significantly improve the recovery of ground temperature[9-11]. Liquefied natural gas (LNG) needs heat in the process of gasification...

... that is largely composed of clay deposits often encounters complex geological conditions exemplified by confined aquifer layers. The encountered aquifers can bear confined water with high pressure (i.e., artesian aquifer) that can trigger seepage towards shield face if a sufficient piezometric head...

... to such complex wells. Therefore, a calculation method is developed. Based on the Dupuit assumption, the vertical velocity of groundwater is ignored, and only the horizontal flow is considered. Consequently, each layer is assumed to be independent of the other during seepage. The water inflow and the water...

... of a cavern. In this paper, a three-dimensional physical model is designed to apply the stress field and seepage field, simulating the whole life cycle from excavation to operation. The experimental model obtains parameters of rock deformation and stress, water inflow, and seepage pressure. All...

... is 93.5 × 40.0 m, and the maximum excavation depth is nearly 85 m, making it a large underground cavern. The project site is in a karst area with a complex geological environment, and multiple faults cross the main pump house. As a result, the groundwater seepage field affects the stability...

For the purpose on hydraulic behaviors control, the authors applied the 3-dimensional groundwater simulation model to estimate the hydraulic behaviors (e.g. pore-pressure dropping, seepage) while excavation and compared with the monitoring data for evaluation. The evaluation...

The Ajanta caves has deteriorated over the centuries due to human and natural causes such as weathering, erosion and seepage in rainy season, which has led to large areas of collapse at various historic times. It was found that the geological discontinuities contribute towards instability of the Ajanta Caves...
