土壤抗冲系数测时标准问题探讨

鉴于目前国内外在次冲刷过程中土壤抗冲系数测时标准问题的空白研究现状,本文从土壤抗冲系数的概念出发,以实验测试数据为基础,采用过程分析和统计分析相结合的方法,初步建立了次冲刷过程中土壤抗冲系数历时变化的计算模型,并作为确定土壤抗冲系数测时标准的理论依据;在此基础上提出了抗冲中值与中值历时的概念与计算方法,并作为各地各类土样抗冲系数测时选择的标准与分析对比的基础.

A Discussion on Time Eclectic Criteria of Soil Anti-scour Index Test

Faced with the current situation of blank study at present on time eclectic criteria of soil anti-scour index test in water-scour process at a time at home and abroad,begun with the definition of anti-scour index and based on the field test data analyses,the calculative models of time variation rules of the index as the academic foundation of confirmation time eclectic criteria of soil anti-scour index test are set up in the article by the means of combination of process mechanism and statistical analyses,then the conceptions and calculative formulas of Anti-Scour Median and Median Corresponding Time are firstly put forward for the data contrast base and time selective criteria of field test of anti-scour index of various soil specimens.
