摘要： PROBLEM TO BE SOLVED: To provide an underground steel bearing wall structure which can suppress subsidence of a banking of a dam body or the like or an inclined ground caused by a liquefaction phenomenon and is easily constructed, and a method for constructing the underground steel bearing wall structure.SOLUTION: Underground steel walls 3, 3 in two rows are arranged in parallel to each other in a banking 1 such that lower ends thereof reach a bearing layer 12 of a ground, and steel barriers 5 are provided between the underground steel walls 3, 3 facing each other at a nearly right angle to the steel wall 3. The steel barrier 5 has a shorter vertical length than that of the underground steel wall 3, and is provided so that a lower end thereof is positioned above a lower end of the underground steel wall 3. Therefore, even when liquefaction phenomenon occurs in the ground in the case of an earthquake or the like and soil is apt to flow in the banking in the continuous direction of the underground steel walls 3, such flow can be restricted by the steel barriers 5 and also the flow of soil in a direction orthogonal to the underground steel walls 3 can be restricted by the underground steel walls 3. Thus, since the flow of soil in the banking can be restricted, subsidence of the banking 1 can be suppressed.
