Web29 de mar. de 2024 · The groundwater around the tunnel consists of Quaternary pore water, karst water and fissure water. ... Subsequently, the groundwater progressively saturated the dry rock, decreasing the strength of the surrounding rocks and turning them into weak and loose rocks. Especially for rocks in the F2 fault, ... Pore water pressure (sometimes abbreviated to pwp) refers to the pressure of groundwater held within a soil or rock, in gaps between particles (pores). Pore water pressures below the phreatic level of the groundwater are measured with piezometers. The vertical pore water pressure distribution in aquifers can generally be assumed to be close to hydrostatic. In the unsaturated ("vadose") zone, the pore pressure is determined by capillarity and is also refe…
