SOUND DETERIORATION ESTIMATION PREDICTION METHOD FOR UNDERGROUND BURIED PIPELINE
To provide a sound deterioration estimation prediction method for an underground buried pipeline, that has excellent prediction accuracy.SOLUTION: An attribute function is calculated by referring to a basic information database. The attribute function is a function of a pipe age and a high soundness ratio calculated in a subdivision of an attribute of a sewer pipe span. In addition, a pipe age function is calculated by referring to the basic information database. The pipe age function is a function of a tube age and a high health percentage for all surveyed sewer drain spans. Next, a finite difference between the attribute function and the pipe age function is calculated. Then, a linear discriminant function expression is derived with either one of the pipe age and the pipe age function and the finite difference related to one or more attributes other than the pipe age as explanatory variables, and a discrimination value is calculated for each sewer pipe span to predict deterioration of the sewer pipe span.SELECTED DRAWING: Figure 2
【課題】予測精度に優れた地下埋設管路劣化推定予測方法を提供する。【解決手段】基礎情報データベースを参照して属性関数を算出する。属性関数とは、下水管渠スパンの属性の細分域で算出した管齢と高健全度割合の関数である。また、基礎情報データベースを参照して管齢関数を算出する。管齢関数は、すべての調査済み下水管渠スパンを対象とした管齢と高健全度割合の関数である。次に、属性関数と管齢関数の差分を算出する。そして、管齢及び管齢関数のいずれか一つと、管齢以外の1つ又は複数の属性に係る差分と、を説明変数とする線形判別関数式を導き、それぞれの下水管渠スパンに判別値を算出して下水管渠スパンの劣化を予測する。【選択図】図２
