Abstract
This paper introduces the basic principle and method of MALA ground penetrating radar for retaining wall detection. Through detection of a retaining wall whose thickness is known in the field, wave speed value of this kind of retaining wall is found; and depending on actual project, characteristics of radar images corresponded to retaining walls with different diseases are summarized. The results show that with application of ground penetrating radar detection technology, defects of wall thickness, full extent of mortar at bed joint, compaction degree of backfill at the back of the retaining wall, could be found effectively.关键词
