通过击实试验和击实后土样的压缩和剪切试验研究红黏土的变形和强度特性。
The deformation and shear strength of lateritic clay are studied by compaction tests and shear tests.
红黏土临界动应力随含水比的增大线性减小，随围压、固结比的增大线性增大。
The critical dynamic stress decreases linearly with the increase of water content ratio, and increases linearly with the increase of confining pressure and consolidation ratio.
