The quality of large quantities of retaining wall made of mortar and stones should be examined rapidly. Based on the comparison of elastic wave velocity, Rayleigh surface wave and elastic wave frequency spectrum analysis, the author holds that the last technique has the merits of high resolution and simple operation. The tests made at several hundred points prove to be successful.
