【摘要】：结合清淤整治工程实践,针对技术管理人员在底泥方量换算时产生较大误差的原因进行分析研究。以土力学中土颗粒、水体、空气的三相比例关系为依据,推导出合理实用的底泥计量换算公式。在此基础上,结合换算公式在某工程中的应用实例,确定了底泥平均含水率的合理计算方法,同时,提出了不同定义含水率间使用注意事项及其计量换算公式的适用性与隐含的约束条件。研究成果对清淤整治工程科学计量具有指导与借鉴意义。
[Abstract]:Combined with the practice of dredging and remediation engineering, the paper analyzes and studies the causes of large error in the conversion of sediment volume by technical managers. Based on the three-phase ratio of soil particles, water bodies and air in soil mechanics, a reasonable and practical formula for calculating and converting sediment is derived. On this basis, combining with the application of conversion formula in a project, the reasonable calculation method of the average moisture content of sediment is determined, and at the same time, In this paper, the applicability and implicit constraint conditions of the usage of water content among different definitions and its formula of metering conversion are put forward. The research results are of guiding and referential significance for scientific measurement of dredging and remediation engineering.
