For the anhydrous ridge deep foundation pit with stable soil structure, this paper introduces the deep excavation without support construction method from the construction process, construction points, construction method, the scope of application and the economic benefit analysis in detail. This is a good method to make reasonable use of the excavation slope, make the engineering quantity achieve the right balance. This method greatly accelerates the progress of the project, shortens the construction period, and also saves the supporting material and cost. In addition, this method shows the environmental protection and energy saving benefit and plays a good social benefit in the applied region. This paper hopes the method can be widely applied.
