Abstract

The design and execution of a non-conventional support system for an excavation pit in a slope will be presented in this paper. Because permission of placing ground anchors in neighboring property was not given, panels made by the Deep Mixing method, extending below the level of the planned building, have been constructed. Based on the specifications of the sub soil and groundwater condition the design concept as well as analytical and numerical calculations will be discussed. The main focus is put on the construction procedure and problems during the execution of the panels. Results from deformation measurements during the construction of the panels and the excavation of the pit will be presented and discussed. In a short summary the main lessons learnt from this difficult case history will be presented.
