摘要
文中根据正态分布概率模型,给出了土坝施工质量控制中回填土密实度的控制标准建议值,并建立了质量控制图,通过质量控制图法,不仅可以检验施工中出现的不合格样品,更重要的是预告不合格样品出现的原因,从而采用必要措施加以控制。
Based on the probability model of normal distribution of earth backfilling density,this paper put forward the recommended value of the density standard controlling.Through the method of quality control,the unqualified samples can be checked,and the causes of unqualified samples can also be announced so that some measures may be adopted to control them.
