疏浚过程中疏浚黏土起球判别指标确定

Determination of index of dredged clay ball in the process of dredging

对黏土成球判别指标进行探讨,分析现有指标的优势和缺陷,通过收集近几年天津航道局疏浚工程典型起球黏性土物性指标,应用数理统计的方法,对起球黏土的物理力学指标进行相关性分析,结合天航局工程实际,总结出一些值得借鉴的疏浚黏土起球判别指标,并利用实测值对疏浚判别指标进行验证,表明该判别指标在一定范围内的适用性。

This paper studies the discrimination indices on the ball clay, and analyzes the advantages and defects of the existing indices. Collecting the physical and mechanical indices of the ball clay from the recent years＇ waterway dredging engineering of TDC, this paper analyzes the data by correlation, variance analysis, and comparative statistics. Combining with the engineering practice of TDC, this paper sums up some indices on the ball clay, based on which, the discrimination indices, which shows the applicability in a certain range, is verified with the measured values.
