摘　　要：无序人工河道采砂导致前坪水库料场筑坝砂砾料级配范围变化大、离散性大,为进一步明确上坝料级配包线,科学确定碾压施工参数,提高施工工效,验证设计填筑标准的合理性,在选定26 t自行式振动碾条件下,对扰动筑坝砂砾料进行了不同铺厚、不同碾压遍数和不同洒水情况组合的现场碾压试验。在试验基础上,提出能够满足填筑标准的高效碾压施工参数及相应的质量控制措施。The gradation range of gravel materials in the dam site of the Qianping reservoir is large, and with large dispersion due to artificial sand excavation. In order to further clarify the gravel gradation envelope of dam, scientifically determine the roller compaction parameters, improve the construction efficiency, and verify the rationality of design filling criteria, field compaction tests with different thickness, rolling times and sprinkling quantity were carried out under the 26t self-propelled vibratory roller. Based on the experiments, it is suggested that efficient compaction construction parameters and corresponding quality control measures can meet the filling criteria.
