| Summary: | 碩士 === 逢甲大學 === 土木工程所 === 96 === The problems of littering and burying of general as well as building wastes by the public have always been a major concern, as causing severe contamination of both soil and underground water. For wastes buried in the past, without their correct information, it is often difficult to accurately locate the exact location and the depth of burial. Since GPR can provide the advantages of fast investigation non-destructively with high resolution imaging of underground structures, it may be applicable for detecting underground waste.
In this study, general buried wastes were considered as the investigation target, and an in-situ buried site and two small-size models were investigated in order to evaluate the feasibility of applying GPR to issues related to detection of underground buried wastes. The study was conducted in two experimental phases to mutually verify correlation between the in-situ site and two models. The experiment was first implemented on two models, where the middle layer is either a hollow layer or a buried waste, respectively. Then the in-situ test was carried out on a landfill site with underground waste to verify and evaluate the GPR results.
The results of the study showed that GPR can precisely determine the coverage of underground buried waste. Furthermore, the location of buried waste can be correctly plotted and determined with the assistance of 3D images.
