| dc.description.abstract | The measurements were conducted on the floors of Serpentine quarries in the Ruey-shin and Jiin-chang quarries, Hua-lian, eastern Taiwan. The aim is concentrated to the fracture distribution inside the outcrops. The Ground-penetrating radar (GPR) survey lines were parallel to each other by an equal distance on the surface of the outcrop of serpentine. Then a three-dimensional (3-D) picture of fracture distribution can be recognized.
In Mei-lun industrial estate, Hua-lian, some well-cutting rock samples were being studied, an optimum deploying of survey lines with proper data processing, the main fractures of a rock sample can be detected.
From the demonstration in this research, it indicates that GPR survey does provide the information related to the quality of the quarry or rock sample. In addition, it also has the advantage of saving time and money in an early stage of an excavation.
A Study of Fractures of Serpentine Quarry by Using GPR

ABSTRACT
There are many successfully case studies of using Ground- penetrating radar technique (GPR) to geologic description and civil engineering. Application of Ground-penetrating radar technique recently has been proven to be effective in defining the extension of fracture zones in a marble or gneiss quarry. Ground-penetrating radar technique is applied to study the fractures of serpentine quarry.
The experiments were conducted on the floors of Serpentine quarries in Ruey-shin and Jiin-chang quarries, Hua-lian, eastern of Taiwan. We observed fracture spread on outcrop and using Ground-penetrating radar by equal rank exploration investigated into the inner fractures of serpentine rock and recognized fracture signals or environment noise. In Mei-lun industrial estate, Hua-lian, the model studying of serpentine cube in serpentine workshop was comparable with the study result on the floors of quarries.
By using an optimum survey design and a proper data processing, the fractures of serpentine rock can be detected. Therefore, using a GPR survey previous an excavation in a quarry has the advantage of saving time and money. | en_US |
