1 导引 淮河入海水道是我省跨世纪的宏伟工程,已在淮阴市境内试挖其防洪堤的标准为一、二级(南堤级、北堤二级) 堤身的施筑,其干密度要求达到规范标准(百分之百达1.5t/m~3以上)。根据试挖段的情况,该段堤身的施筑土料要求5-1类土(粘土)、1～2类土(砂壤土),目前土料的天然含水率不等,均在16%～29%之间。针对不同的土料、不同的含水量,机械碾压遍数多少时堤身可以达到规定的干密度,是一个值得探讨的问题。 要控制好堤身的质量,首先应明确控制上堤土料的含水量以及最优含水量,机械碾压遍数为多少时
1 Guiding the Huaihe River into the sea is a magnificent cross-century project in our province. It has been tested in Huaiyin City to test its levees for the first grade and the second grade (Nandi grade and Grade II) Density requirements to meet the standard (100% up 1.5t / m ~ 3 above). According to the trial dig section, the construction of the section of the dike requires soil class 5-1 (clay), 1 to 2 types of soil (sandy loam), the current natural moisture content of soil ranging from 16% 29%. According to the different soil materials, different water content, the number of mechanical rolling embankment can reach the required dry density, is a question worth exploring. To control the quality of the embankment, it is first necessary to clearly control the water content of the embankment material and the optimal water content. When the number of mechanical rolling passes
