| Abstract: | This paper concerns the construction of Minzhi Metro Station which has a serious eccentric compression problem due to the adjacent existing Pingnan Railway. To ensure the operation safety of Pingnan Railway and the safety of construction, the steel pipe pile and sleeve valve pipe grouting are adopted to strengthen the embankment on the side of Pingnan railway, meanwhile designed width of the diaphragm wall is optimized to 1.2 m and the designed depth of entering rock is increased. The excavation of deep foundation pit must obey such rules as upright slice, longitudinal divisions, and rapid bracing after excavation. |
