摘　　要：动态空心圆柱扭剪仪(HCA)是目前国内外公认的最复杂、最尖端的室内土动力学试验设备。为了配合空心圆柱扭剪仪重塑样的制样,依据传统三轴重塑样击实器的原理,研制了空心圆柱重塑试样的击实器,来控制重塑样的相对密度和均匀度。实践证明,击实器可以满足重塑样制样的需要。Dynamic hollow cylinder apparatus （HCA） is the most advanced and complicated device in lab-testing on soil dynamics. To make reconstituted samples in hollow cylinder apparatus, a compacting instrument was developed according to the principles of the compacting tool used for traditional triaxial reconstituted samples. It is demonstrated by practical experiences that the remolded samples made with the instrument show good uniformity and well-controlled relative density, which can meet the sample preparing requirements very well.
