在我国,通常采用圆锥法来确定流限,其试验方法有两种:一种是调试法,即多次调配含水量试验,使圆锥沉入土中深度恰为10毫米。这种方法工作量较大,费时且不易操作;另一 In China, the cone flow method is usually used to determine the flow limit. There are two test methods: One is the debugging method, that is, the water content test is repeated several times to make the cone sink into the soil to a depth of 10 mm. This method has a large workload and is time consuming and difficult to operate;
