Low Carbon Optimization of Deep Foundation Pit Support in Undulating Strata

To mitigate carbon emissions during the construction of deep foundation pit support in undulating strata, a theoretical calculation approach was utilized to design and compute for Qingdao’s Metro Line 4. On this basis, numerical simulation method is used optimize scheme with surface deformation stress structure. The results show that final ground settlement 5.26 mm, maximum horizontal displacement 0.2836 corresponding shear force retaining pile 250 kN, which obviously superior 55 33 1341.03 kN design. use software before excavation can reduce resource waste achieve low-carbon while ensuring safety.
