这里谈谈工地土壤含水量的快捷测定及在现场用塑性指数鉴别土壤分类的方法,提供参考和讨论。一、含水量的快捷测定用一个碗(或四方形的小容器)盛满水秤之,得一重量,以W_1表示之(等于碗加满碗水重);在工地拾一块比盛器小的湿土,秤之,得一重量,以W_0表示之,再将此湿土放入碗中加水至满,连碗秤之,得一重量W_2。则因 W_1=碗重+满碗水重 Here to talk about the quick determination of site soil moisture and plastic index in the field to identify soil classification methods for reference and discussion. A quick determination of water content with a bowl (or small square container) filled with water scale, have a weight, expressed as W_1 (equivalent to bowl filled with bowl of water); picked up at the site a smaller than the container Wet soil, scales, have a weight, expressed as W_0, and then put this wet soil into the bowl full of water, and even a bowl of scales, have a weight W_2. Because of W_1 = bowl + full bowl of water weight
