摘　　要：文中以实际工程为依托,对胶凝砂砾石的施工定额消耗情况进行分析。结合现场实测数据,采用Bootstrap模拟产生的伪数据子集对整体样本进行分析。结果表明,Bootstrap模拟得到的分析结果与蒙特卡洛方法结果非常接近。文中分析方法为胶凝砂砾石坝施工定额消耗估计提供了可靠的解决路径,为胶凝砂砾坝体的推广的施工定额消耗分析提供了有效分析手段。Based on the actual project, this paper analyzes the construction quota consumption of cemented sand& gravel. Combined with the field measured data, the pseudo data subset generated by bootstrap simulation is used to approximate the whole sample. The results show that the results of bootstrap simulation are very close to those of Monte Carlo method. The analysis method in this paper provides a reliable solution for the estimation of construction quota consumption of cemented sand& gravel dam, and provides an effective analysis method for the popularization of construction quota consumption analysis of cemented sand& gravel dam.
