摘要： 水库坝体垫层料的压实质量是控制坝体稳定、沉降变形和防止面板裂缝的关键，为保证张河湾水库坝体垫层料的质量，施工前需进行垫层料的现场碾压试验。通过现场碾压试验，了解影响垫层料压实质量的因素，确定最佳碾压参数，为坝体垫层料的施工提供了科学依据。

Abstract: The compaction quality of a reservoir dam is crucial to control the stability and subsidence of dam body and to prevent the cracking of the facing panel. To ensure the quality of cushion material of Zhanghewan upper reservoir dam body, a trial compaction on the cushion materials was performed before the construction. Throughout this trial compaction, factors that might affect the degree of compaction of cushion materials were investigated. Compaction parameters were able to be optimized.
