| Abstract: | The inverted perpendicular, being a deformation monitoring datum with large-scale building, is widely applied to the water resource projects. It is the first time with the 110 m depth inverted perpendicular's setting. The ultra deep inverted perpendicular is successfully set by engineering test and feeling about the construction experience and groping the key and adopting the new setting techniques. The systemic applied construction setting scheme is summed up in the end. |
