摘要：
A method is presented for the calculation and verification of soil layer compaction strength values from in situ plate sinkage data, as compared with traditional laboratory compression testing of confined soil cores. Experiments were conducted in a prepared soil bin by compression loading with a portable soil plate penetrometer for the unconfined plate sinkage tests and by confined uniaxial tests on soil cores. It was shown that soil compaction strength determined from unconfined in situ plate sinkage tests was statistically similar, at the p = 0.05 level, to results from paired confined tests. This result suggests that both methods can be applied interchangeably. Therefore, the relative ease of conducting in situ plate sinkage tests may be an attractive alternative for field compaction studies.
