| 摘 要： | 盾构隧道的纵向力学与变形性态研究,尤其是盾尾壁后注浆效果已经引起国内外学者的广泛关注,笔者首次利用探地雷达方法,对上海某盾构隧道盾尾壁后注浆分布进行探测,并进行了初步的分析,结果表明,利用该方法可有效地探测隧道壁后的注浆分布,为隧道纵向力学变形性态的控制提供一定依据。

| Abstract: | Recetent years, the increasing attention to the longitudinal settlement in shield tunnel is paid in the world. And the grouting behind segment at the tail is more focused on for controlling the surface settlement. in this paper, GPR (ground penetrate radar) method was firstly introduced to detect the grouting distribution and thickness behind segment in Shanghai metro. some analyses on obtained graph were done, and show the detail distribution of grouting. this simple study proposes a good way for GPR to detect grouting in shield tunnel, and it is possible to control ground settlement more perfectly. |
