因果分析图法在土方压实度质量控制中的应用

Application of causality diagram method in quality control of earthwork compaction degree

在淮安市淮河入海水道二期工程建设管理过程中,针对“堤防填筑压实度”这一关键质量问题,项目建设管理团队采用QC小组活动方式,利用因果分析图法分别从土质、环境、人员、方法、机械等5个方面逐层分析影响土方压实质量控制的主要和次要原因,有针对性地提出各项处置和预防措施。经实际应用质量控制效果良好,土方压实各项指标均满足规范要求,该方法有效促进了工程施工流程的规范化、标准化管理,有推广应用价值。

In the process of the construction management of the second phase of the Huai'an Huaihe River Sea Inlet Project,the project construction management team adopted the QC group activity mode to address the key quality problem of“compaction of embankment filling”,by using the causality diagram method.This paper analyzes the main and secondary reasons influencing the quality control of earth compaction from five aspects:soil quality,environment,personnel,method and machinery,etc.,put forward the disposal and preventive measures.After practical application,the quality control effect is good,and all the indexes of earth compaction meet the requirements of the code.This method effectively promotes the standardization and standardized management of the construction process and is worthy of popularization and application.
