Y=0.816*16.8-5 = 8.7% ??是这样吗??Ï

应该是 Y=0.816*16.8-5 = 8.7%Ï

16.8% 要是带进公式的话把百分号去掉就是0.168了.Ï

桥涵用砼粗集料压碎值也应该换算.Ï

水泥混凝土上要用该公式进行换算，用该公式换算为GB/T 14685-2001中压力为200KN的压碎值，400KN是用于沥青混凝土路面用碎石或二灰碎石基层中压碎值所用的最大压力Ï
nkRFbbs.3c3t.com©öJÞ@½¡Ã×
lllliiiiuuuujun - 2008/5/5 16:54:00
就是用JTG E42-2005中压碎值试验方法（40KN）所得结果*0.816-5，即可换算为GB/T 14685-2001试验方法所得压碎值Ï

Y=0.816*16.8-5 = 8.7%是对的Ï
nkRFbbs.3c3t.com©öJÞ@½¡Ã×
fuzhengjun - 2008/5/8 17:39:00
Y=0.816*16.8-5 = 8.7%是对的，如果按Y=0.816*0.168-5 = -4.86%，不成立的。计算时只去掉%就行，不必换算成0.168，否则就不对了。Ï

你说的200KN和400KN所用的公式能具体说明一下吗？谢谢了。Ï

メ逍遥浪子メ - 2008/6/8 20:25:00
这个正确，Y=0.816*16.8-5 = 8.7%，只要是集料试验就要换算。Ï

xltxl - 2008/7/5 20:53:00
只要是水泥混凝土都要换算 还分什么桥梁吗。。。木头的桥梁不用。。。X指的就是你算出的压碎值16.8 0.816*16.8-5Ï
nkRFbbs.3c3t.com©öJÞ@½¡Ã×
你别光看公式 公式前面的解释你也要仔细看。。我也是自己看的。Ï
nkRFbbs.3c3t.com©öJÞ@½¡Ã×
xltxl - 2008/7/5 20:55:00
公路试验检测的试验规程上 已经没有200KN的了 都是400KNÏ
nkRFbbs.3c3t.com©öJÞ@½¡Ã×
只不过是为了换算成 施工规范上要求的压碎值而已 所以水泥混凝土的要计算一下Ï
