The soil was strengthened in some areas by mixing in durable clays, and relief wells were dug on the protected side of the wall to reduce seepage pressure.
Variations of seepage pressure and grout propagation were compared in our investigation.
The asynchronous injection production mode has negative effects on pillar stability and seepage pressure, particularly for narrow pillars.
However, the seepage pressure propagated within a relatively narrow area: a slope distance of ∼4 m from the seepage point in the downslope direction due to the damping of seepage pressure.
The surrounding rock will experience more water pressure and seepage pressure, and, at the same time, the area of the plastic zone grows.
Vertical stress, deformation, plastic zone, safety factors, and seepage pressure of pillars between two adjacent salt caverns are discussed, and the allowable width of the pillars is optimized.

According to design precedence, all slope remediation applications that use geofoam blocks should incorporate permanent drainage systems to prevent instability of the lightweight geofoam blocks due to hydrostatic and seepage pressures.
The relationship between seepage velocity and pressure gradient is obtained and fitted by the nonlinear Forchheimer formula.
(6) Open image in new window Fig. 7 Typical relation curves of seepage velocity and pressure gradient in low-permeability reservoir.
During the development of high-sulfur gas reservoirs at water drive gas, the water body flows to the gas reservoir, forming a gas water two-phase seepage with decreasing pressure.
The results show that a low-permeability mudcake enhances FIP, mainly through restricting fluid seepage and pore pressure increase in the near-wellbore region, rather than by mudcake strength.
