关于变水头渗透试验计算工作是比较复杂的,同时很不大众化,既要查对数表,又要查水温校正系数,特别是在小数点定位上,容易出问题。对一位数学基础较差的试验员说来,确实困难不少,难免不发生错误,为了解决这个问题,茲将我在这方面所设计的一种图表,提供大家研究。一、本图表的使用方法:本图表共计九条线,(见附图)(见插页)。编号为1至9均与中线5对称,查法是根据之商值在线5上寻找这点所在位
On the variable head penetration test calculation is more complex, while very popular, it is necessary to check the log table, but also check the water temperature correction coefficient, especially in the decimal point positioning, prone to problems. To a tester who has a poor mathematical foundation, it is really a lot of difficulties and it is inevitable that there will be no mistakes. To solve this problem, we will give you a chart that I have designed in this regard. First, the use of the chart: This chart a total of nine lines, (see photo) (see insert). No. 1 to 9 are symmetrical with the center line 5, the search is based on the value of online 5 to find the location of this bit
