THE USE OF SEISMIC REFRACTION IN A ROUTE FEASIBILITY STUDY IN ST LUCIA

AS PART OF A FEASIBILITY STUDY OF ALTERNATIVE LOCATION FOR A TRANS-ISLAND ROAD LINK IN ST LUCIA, A SEISMIC REFRACTION TECHNIQUE WAS USED TO ESTIMATE SOIL DEPTHS TO BEDROCK AT RELATIVELY INACCESSIBLE SITES WHERE EXTENSIVE CUTS WOULD BE REQUIRED. A DESCRIPTION IS GIVEN OF THE SITES AND OF THE METHOD OF INVESTIGATION; DETAILS ARE INCLUDED OF PRACTICAL EXPERIENCE GAINED IN THE FIELD. THE RESULTS SHOW THAT WHEN DRILLING IS IMPRACTICABLE, SEISMIC REFRACTION OFFERS A SATISFACTORY ALTERNATIVE MEANS OF QUICK SUB- SURFACE EXPLORATION THAT IS SUFFICIENTLY ACCURATE TO PERMIT COMPARISONS TO BE MADE BETWEEN ESTIMATES OF THE COST OF EARTHWORKS ON SEVERAL PROPOSED ALIGNMENTS.
