Abstract

下水汚濁した海底堆積泥の環境改善実験が行われており,浄化機構の解明や現場実験結果の評価のために様々な手法が用いられている.本論文では,超軟弱泥上に構築された石炭灰造粒物層での観測方法を検討するとともに,底質改善を評価するための調査手法,具体的には,超軟弱泥層での沈下実験,ヘドロ厚さ測定,軟弱有機泥の性状評価のための新しい手法について提案し,現地調査に用いた.これらの調査結果から本手法は超軟弱泥層での底質改善を評価するために適した手法であることが明らかとなった.

 The environmental improve experiment of marine pollution due to the eutrophication of the sea bottom sediment has been done. Then, various methods have been used to understand the mechanism of purification and to evaluate the results of the field experiment. In this paper, the observation and evaluation methods for covering sea bottom sediment by GCA were considered. And, new observation methods to evaluate the environmental improvement were used. The new methods for the sinking experiment of GCA layer, the measuring of sludge depth, the evaluating of GCA effects were produced. These results make clear that these are suitable methods for the evaluation of GCA covering technique.
