Abstract

<p>近年問題となっている道路陥没は,路面下の空洞が原因である.道路陥没の予防・対策に当たって路面下空洞の生成要因や成長状況を把握する必要がある.本研究では,福岡市より実際の路面下空洞データを提供いただき,QGIS 上で地形,交通量などの各種地図データ,地下埋設物との位置関係などと比較.空洞の生成状況との相関を評価した.加えて,空洞が頻発する箇所および成長した箇所の共通点を挙げるとともに大まかに空洞の発生・成長速度を算定した.</p>

<p>A number of cavities develop below the roads. Subsurface cavities gradually grow and when they reach near the surface, the road depression or cave-in may happen.</p><p>In this study, data of subsurface cavities obtained in Fukuoka city were examined with some geographic factors such as landform, traffic and underground structure using GIS. It was found that landform and sewer pipe affected on cavity formation. Furthermore, the growing speed and volume of some cavities were calculated.</p>
