Deformation characteristics of a 38 m deep excavation in

To meet the increasing demand for underground space for economical development and infrastructural needs, more and more deep excavations have been constructed in Shanghai. In this paper, field performance of a 38 m deep multistrutted excavation in Shanghai soft clay is reported. The deep excavation was retained by a 65 m deep diaphragm wall.

Numerical Analyses of the Multi-propped Excavation in Soft

Together with the case history documented in this study and eight others reported in the literature (Liu et al. 2005; Wang et al. 2005; Tan and Wei 2011; Liu et al. 2011), it is found that excavation-induced ground deformation in Shanghai soft clay is relatively smaller than similar excavations in soft clay worldwide (Long 2001; Moormann 2004).

Deformation characteristics of a 38 m deep excavation in

Nov 22, 2011 · Because of the significant stress relief resulting from the 38 m deep excavation, maximum heaves of the center column and diaphragm wall panel were about 30 and 16 mm, respectively. The measured ratio δp / H (heave/final excavation depth) of column is less than 0.1% whereas the observed δp / H of the diaphragm wall panel is about 0.04%.

Study on Effects of Ground Deformation Based on Foundation

With the continuous development of urban underground space, the environmental effects of foundation pit excavation have been paid extensive close attention. Unfortunately, there are few researches in mucky soil and peaty soil. Adopted the software of FLAC-3D, the ground deformation due to the foundation pit excavation is simulated. Considering the characteristic …
