Underground works were located below the water table. The impact of groundwater on underground works especially, whether design or construction or normal operation, and control of groundwater must be considered on the adverse effects of underground works.

Underground project located in many groundwater levels following. Underground water to the underground works particularly affected, and whether it is the design or construction or is running correctly, it must be taken into account and the control of groundwater in underground works negative effects

The underground project is located below much the subsoil water level.Ground water to underground project influence outstandingly, regardless of is the design or constructs perhaps the normal operation, all must consider and controls the ground water produce to the underground project affects not go

Underground engineering on the ground floor below the water level. Influence of groundwater on underground engineering particularly notable, either the design or the construction or functioning, must take into account the adverse effects and control of groundwater on underground engineering.

The underground project lie under water table more. The impact on underground project of the groundwater is particularly outstanding, whether no matter design and operation or normal running, must all consider and control the harmful effects that the groundwater produces the underground project.
