| Abstract: | The biggest excavation depth of open excavated foundation pit in Xi'an Narth Station main body is 18.7 m,with some parts 21 m.The geological layers are divided into three from top to bottom: clay,loess-like clay,fine silt and medium coarse sand.The designed support is bored cast-in-situ piles plus anchor.Anchor in sand layer pore-forming is a key to the support construction.This article elaborates in detail the anchor design and construction techniques. |
