آشکارسازی حفره های زیرسطحی به روش مقاومت ویژه Bristow

Electrical resistivity method is a suitable tool for investigation on subsurface inhemogenities including subsurface cavities and karst. One kind of resistivity configurations for detection of subsurface cavities is Bristow method. In this method, Pole-Dipole array and a graphical technique for interpretation of field data are applied. The aim of this research is evaluation of Bristow method in detection of subsurface cavities and comparing it with other linear resistivity arrays. Comparisons among different resistivity arrays confirm that Bristow method is an applied and logical way for detection of subsurface cavities and karst.
