METHOD FOR EVALUATING HORIZONTAL RESISTANCE OF UNDERGROUND STRUCTURE

PROBLEM TO BE SOLVED: To more accurately evaluate the horizontal resistance of an underground structure surrounded by a soil cement wall whose upper part is at least formed as an earth retaining wall, and integrated with the soil cement wall.SOLUTION: The evaluation method of the horizontal resistance of a pile 10 surrounded by a soil cement column row wall 20 whose upper part is formed as an earth retaining wall, and integrated with the soil cement column row wall 20 is characterized such that a valid width D for evaluating the horizontal resistance of the pile 10 is set to a width d' calculated by adding a diameter d of the pile 10 to the thickness of the soil cement column row wall 20 at both sides.
