摘要

近年来,人们发现越来越多的城市地面沉降事件。这种情况主要是由于地下洞室数量的增加。本研究旨在发展防止因下水道恶化或损坏而引起地面沉降的方法,这是地面沉降的主要原因。为此,在沉降潜力较大的地段,利用闭路电视监测劣化下水道进行探地雷达勘探。通过CCTV监控和探地雷达调查,在下水道损坏、接缝开裂、积土的现场,监测到异常的地面行为。根据本研究的现场调查,利用闭路电视监控和探地雷达调查结果的相关性分析的评价方法,有望防止因下水道损坏引起的地面沉降。

Analysis of Sewer Pipe Defect and Ground Subsidence Risk by Using CCTV and GPR Monitering Results
Recently, increasing number of urban ground subsidence occurrences has been identified. This situation is mainly due to the increased number of underground cavities. This study is intended to develop the method that prevents ground settlement caused by deteriorated or damaged sewers, which are the main cause of land subsidence. To that end, GPR exploration was conducted using CCTV monitoring of deteriorated sewer at the location with high settlement potential. Through such CCTV monitoring and GPR investigation, abnormal ground behavior was monitored at the site where sewer was damaged, joint was cracked and soil was deposited. According to site investigation in this study, evaluation method using correlation analysis of CCTV monitoring and GPR investigation results is expected to prevent ground settlement attributable to damaged sewer.
