METHOD AND APPARATUS FOR PREDICTING MAXIMUM AND MINIMUM FLOW OF LEAKAGE CONTAINING SEAWATER IN UNDERGROUND WATER, AND METHOD AND APPARATUS FOR PREDICTING MAXIMUM AND MINIMUM FLOW OF SEAWATER OR UNDERGROUND WATER FLOW IN LEAKAGE CONTAINING SEAWATER IN UNDERGROUND WATER
PROBLEM TO BE SOLVED: To easily acquire predicted values of maximum flow and minimum flow of leakage containing seawater leaking to an underground structure without performing complicated hydraulic computation.;SOLUTION: The flow of the leakage containing seawater, and sodium ion concentration are measured. These measured values are substituted in expressions [sodium ion concentration] = k/[leakage flow] (4) and [sodium ion concentration] = [leakage flow] + (5) to obtain constants k, and . A leakage flow value acquired by substituting the value 0 for the sodium ion concentration of the expression (5) is set as the predicted value A of maximum leakage flow, and the leakage flow value acquired by substituting the sodium ion concentration value of seawater for the sodium ion concentration of the expression (4) is set as the predicted value B of seawater flow in the leakage. A sodium ion concentration value C is obtained by substituting the predicted value B for the leakage flow of the expression (5), and the leakage flow value obtained by further substituting the sodium ion concentration value C for the sodium ion concentration of the expression (4) is set as the predicted value D of minimum leakage flow.;COPYRIGHT: (C)2004,JPO
