Abstract

The objective of this study is to evaluate the strength and volumetric water content of ground using an instrumented TDR dynamic cone penetrometer (ITDP). The ITDP, which is developed to simultaneously measure two parameters on a borehole, is installed by an accelerometer, strain gauges, and electrodes. ITDP tests are carried out for ground up to a depth of 700 mm under rainfall conditions, and the two parameters are measured according to time (0 h, 3 h, and 9 h). Generally, the strength of the ground decreases and its volumetric water content increases after the rainfall. The decrement of the strength and increment of the volumetric water content at 3 h are greater than those at 9 h until a depth of 150 mm, while those at 3 h are smaller than those at 9 h beyond a depth of 150 mm. Thus, ITDP may be effectively used to profile the strength and volumetric water content of ground.
