问题 问答题 案例分析题

案例背景材料:

某段土方填筑路基施工完成之后进行了压实度和弯沉值检测,压实度采用环刀法。弯沉采用贝克曼梁法。

问题:

1、弯沉测试除贝克曼梁法外还有哪些方法?2、压实度的检测方法还有哪些?其中规范规定的试验方法是什么?

答案

参考答案:

1、弯沉测试除贝克曼梁法外还有自动弯沉仪法和落锤弯沉仪法。

2、压实度的检验方法有灌砂法、核子密度湿度仪法。规范规定的试验方法是灌砂法。

考点解读:

压实度是路基质量控制的重要指标之一,是现场干密度和室内最大于密度的比值。压实度越高、路基密实度越大,材料整体性能越好,其现场密度的测定方法有:灌砂法、环刀法、核子密度湿度仪法。

      It was December 25. Marie, a 13-year-old Australian girl, was happy. It was Christmas, and Marie's

mother was making a special cake. She put four small coins into the cake, and then she baked (烤) it. The

four coins were for good luck. After dinner Marie and her family ate the cake. They found three coins in

the cake and put them on the table. Where was the fourth coin? It was missing, but Marie's mother didn't

notice.
