Abstract: This paper presents a case history of the design of a deep excavation supporting system of a sports park using Lizheng geotechnical design software. The design considered various site conditions and the supporting system design utilized the cast-in-place reinforced concrete pile with three layers of ground anchors. The lateral deflection and the axial loads in the piles were estimated with the software and the results compared with long term monitoring data. The studies concluded that the analytical simulation of the construction process and construction monitoring can provide guidelines for the rest of construction procedures.

Key words: Deep Excavation Supporting Structure, Lizheng Software, Comparative Study between Measured and Estimated Data
