In the recent years, non-connected piled raft foundation has been considered as an economical and practical deep foundation in the situation that high shear and concentrated loads may occur at the connection of the raft and pile head. This paper was presented an experimental study of a square foundation on the effects of parameters such as S/D, L/D and etc. in two cases of connected or non-conn...

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 displacem...

Based on the deep foundation pit project of Laoguancun station Wuhan rail transit line 16 and according to engineering characteristics construction conditions site surrounding environment, method combining field monitoring finite element numerical simulation is adopted analyze law stress deformation during excavation support construction; it includes horizontal displacement underground diaphrag...
