【 摘 要 】

Choosing an appropriate method of deep excavation not only plays a decisive role in technical success, but also in economics of the construction project. Presently, we mainly base on to key methods: "Bottom-up" and "Top-down" construction method. Right now, this paper presents an another method of construction that is "Semi Top-down method combining with earth-bank" in order to take the advantages and limit the weakness of the above methods. The Bottom-up method was improved by using the earth-bank to stabilize retaining walls instead of the bracing steel struts. The Top-down method was improved by using the open cut method for the half of the earthwork quantities.
