Research Abstract

This Study proposes a method of visualization using thermography suitable for the evaluation of execution ability and bearing capacity of the screw pile. The correlation between the temperature distribution and stress appears most clearly by thermography with a sand : clay mixing ratio of 7:3 and with a water content of 7%. And the proper distance from the test samples to the lamp was 60cm and proper heated time was 15seconds. Based on these results, the pile was driven into the soil at 4 different penetration speeds. As a result, it is possible to evaluate the performance of a screw pile and the mobility of soil using thermography images.
