PURPOSE: A method for constructing and repairing a continuous beam bridge by using the rise and fall of an inner support is provided to induce the compressive stress to the concrete of a floor slab by descending an inner support after grouting the concrete while the inner support is ascended. CONSTITUTION: A method for constructing and repairing a continuous beam bridge by using the rise and fall of an inner support comprises the steps of placing plural beams horizontally and vertically on a pier and an abutment, grouting the concrete(4) of a floor slab in 90% of a span, connecting the beams by using a cross beam at an inner support, grouting the concrete in the rest of the span, and descending the inner support.
