盾构隧道施工中同步注浆新材料的实验研究

Experimental Study of New Materials of Synchronic Grouting in Shield Tunneling

位移的大小是综合控制盾构工法的主要参数之一。盾尾间隙引起的地层损失在总的地层损失中所占比例较大,而减小盾尾间隙及其引起的地层损失较为成熟的方法,是在盾尾后部注浆以填充盾尾的间隙,本文就是从注浆材料出发,将不同注浆材料对地面沉降的影响加以对比研究。

Displacement is one of the important parameters in the integrated control of shield tunnelingo Grouting in the back of shield tail to fill the gap and to reduce the stratum loss, which leads to a large percent of the total stratum loss, is a relatively mature method. This paper studied the different ground settlement caused by different grouting materials.
