In this study, thermal and hygric behavior of underground space and the condensation behavior are investigated on moisture damper arrangement of the envelope wall and depth of water table. Nonlinear heat and moisture transfer equations are used as the analytical model. Calculations are performed by explicit finite difference method. The major results are as follows. 1) In the view of preventing the moisture damage of room, the case of the wall with the moisture damper at the outside surface is the best. 2) The case of the wall without moisture damper is better than the case of the wall with moisture damper at the inside surface. 3) Even if the water table is located above the underground space, the surface condensation doesn't occur and room air relative humidity decrease with sufficiently air change rate.
