摘要
国内许多年久失修的地下设施在废弃时面临巨大的安全隐患,而利用高含沙泥浆进行填充是有效而经济的方法。在进行填充前,对管道填充的可行性需要建立模型进行试验研究。在模型试验研究时遇到的模型不相似问题是影响模型试验准确性的重要因素,因此要对试验所得数据进行修正。在本次研究中我们通过对于试验所得流速数据进行糙率纠正解决了糙率不相似的问题。
There are a huge amount of aged underground spaces in our country. And we will face to serious hidden troubles while we are going to abandon them. According to the previous research we found that it could be effectible and economical for us to backfill these spaces with sand slurry. A physical model test is needed before we started the backfill. The dissimilarity between the model and the prototype is a main fact which influence the veracity of the model test. This is the reason why we should correct these data series which we get from the test. And in this test study, we employed the correction of the roughness of the channel bed to solve the dissimilarity problem we met in the test.
