Summary:PURPOSE:To protect a ground structure enough from earth pressure by providing a buttress-type retaining wall on the inner face of a recess being made by excavating the ground, and fixing the batholith with a permanent anchor driven vertically. CONSTITUTION:The ground is excavated vertically, and the flank of the excavation is timbered with shotcrete, a lock bolt, a ground anchor, etc., thus a recess 1 is made. Next, a buttress-type retaining wall 2 is provided at the inner flank 1a of the recess 1, and besides the batholith 2a of the retaining wall 2 is fixed by a permanent ground anchor 6 being driven vertically to the ground. And, an underground structure 7 being structurally cut off the retaining wall 2 is built in the recess 1. Therefore, the earth pressure from the ground is received enough by the retaining wall 2, and the underground structure 7 surrounded by the retaining wall 2 is protected from external force such as earth pressure, etc. Accordingly, the problem in strength of the underground structure 7 is solved, and the safety is secured.
