Description

We had tried to estimate tunnel face stabilization about a new tunnel construction method using prelining and insert deck system. In this report, we carried out a large scale tank test for the purpose of confirming the phenomenon in the ground. As the result, we understood the three-dimensional ground diformation around the tunnel face, and the critical face supporting pressure for the stabilization. And also we confirmed that this method have an advantage in the face stabilization compared with conventional methods.
