摘要
在研究盾构法隧道施工对地层扰动影响的课题中 ,采用了静力触探仪进行原位测试 ,测定了盾构动态推进引起周围土体的比贯入阻力Ps值的变化。针对测试时间、范围、数量有限的特点 ,利用最优分段法对试验数据进行了聚类处理 。
Static cone penetration test has been done to study the effect of shield tunneling on the ground in our research project, and the variation of Ps (specific penetration resistance) also has been measured. In the paper, optimum grouping method is introduced to cluster the test data. The analysis results show the method is effective in data process and also can be for reference on the understanding of the general laws of shield tunneling.
