| Abstract: | Along with the needs of development of underground space, engineering of foundation pit, which is the tech- nical support for underground development, is facing new challenges. This arlicle reviews the characteristics as well as design scheme of sh~dlow foundation pit proiects in Beijing area and analyzes tile features and challenges of urhan oversized deep foun dation pit projects. Combined wilh design, construction practice, monitoring as well as ewduation of an oversized deep founda tion pit project in Beijing, the design concept of oversized deep foundation pit project is summarized and new ideas for develop- ment of foundation pit in Beijing area are raised. |
