There are three primary areas of ground movement towards a pressurised TBM: at the face, along the shield skin and at the tail void -(In the attached figure).
Can the maximum surface Settelment of the tunnel Longitudinal Cross section due to the displacement of the tunnel face can be added with the Transverse cross-section surface Settelment and introduced as the final surface Settelment? in 2D model-numerical method.?
But in the transverse two-dimensional method, we cannot get Settlements dou to face pressure induced by tunnel advanc.
I was going to get the Settlements dou to face pressure from the longitudinal 2D model and add it to the other Settlements Caused by other factors
In the longitudinal section of the tunnel, details and geometries and conditions have been implemented so that only the displacement caused by the face pressure is created and that the shield cone and mortar injection and consolidation are not modeled.
so only max surface settelment in longitudinal cross cestion is occurred due to face pressure It is capable of adding with max surface settelment in transverse cross sestion due to injection pressure and shield cone?
Hello ¶
Normally, we cannot summon two settlements because each one is in a direction;¶ the first it is in the transverse direction and the other follows the axis longitidinal, to see file joint.¶
Hello Miss El Houari
Thank you
Your shape is indistinct
Please presente a valid paper
and that my goal is max surface settelment in two section
