摘要： PROBLEM TO BE SOLVED: To prevent bank breakage due to piping by reinforcing a bank itself and the foundation ground by performing at least one of reinforcing soil and fiber mixing reinforcing soil and its embankment. SOLUTION: Counterweight filling is performed by fiber mixing reinforcing soil 4A on the upper face so that the lower side part 2a of the inside slope of a bank body 1 and a part 3a of a peripheral foundation ground face continuing thereto are covered. The fiber mixing reinforcing soil is a soil quality material obtained by artificially mixing a fiber in sand and soil, excellent in strength characteristics such unconfined compression strength and apparent cohesion, and excellent in characteristics of erosion caused by rainfall or the like and characteristics of scouring caused by water flow. As a result, even when a pipe line leading to the lower side part 2a of an inside slope 2 or the peripheral foundation ground face continuing thereto is formed and grown, the growth of the pipe line can be suppressed since the counterweight fill 4A is strong is scouring. Thereby piping breakage of a bank body of a river, a lake and sea is prevented, and the reinforcement of the bank body is made possible inexpensively and in a short time.

摘要： PURPOSE:To relieve damage to existing structures by suppressing the fluidization of soft ground by a method in which a fluidization preventive wall for soft bearing ground is made up of rigid piles and a water-permeable sheet. CONSTITUTION:Soft ground Al to support an existing structure C is surrounded by a fluidization preventive wall 1 for the ground. The wall 1 consists of rigid piles 2 driven at a given interval around the soft ground A1 and water- permeable sheets 3 in a tensed state set integrally with rigid piles 1 between the adjacent piles 2. The lower ends of the piles 2 and the sheets 3 are driven into the bearing layer B and supported. Void water passes through the sheets 3 and is discharged into the outside soft ground even when liquefaction occurs in soft ground A by the rise of the void water pressure during earthquake. The excessive void water pressure beneath the existing structure C can thus be smoothly dissipated.

摘要： PROBLEM TO BE SOLVED: To predict the advance of compound deterioration due to salt damage and carbonation in a technique for predicting deterioration in a concrete structure. SOLUTION: The deterioration prediction method of a concrete structure predicts the advance of deterioration due to the salt damage and carbonation of the concrete structure by analyzing various kinds of deterioration factors using a finite element method. The progress of compound deterioration is expressed by a chemical reaction expression including a hydration product in concrete and carbon dioxide in the atmosphere at one side and calcium carbonate at the other side, and a reversible chemical expression containing calcium carbonate, an aluminum acid, and chloride at one side, and Friedel salt and a carbon dioxide gas at the other side. The progress is predicted by analyzing diffusion equations (1) and (2) by finite element method. COPYRIGHT: (C)2003,JPO

摘要： PURPOSE:To relieve damage to existing structure by preventing the fluidization of soft ground by a method in which a ground fluidization preventive wall in which many high-rigid piles are closely driven is formed on the surrounding of a soft bearing ground of existing structure. CONSTITUTION:A soft ground A1 to support an existing structure C is surrounded by a ground fluidization preventive wall 1 which is formed of many high-rigid piles 2 whose lower ends are closely driven into the bearing layer B around the ground A1 from the ground's surface along the outside of the structure C. Also, the pile 2 is formed by packing and tamping granular material 4 such as sand or resin grain into a water-permeable long bottomed bag 3 having a diameter enough to reach the layer B from the ground's surface. Void water passes through the material 4 packed into the bag 3 and bags 3 in the pile group and goes into the outside soft ground even when liquefaction occurs in the ground by rise of void water pressure in the soft ground during earthquake.
