IMPACT ASSESSMENT USING FINITE ELEMENT ANALYSIS
EI Australia initially carried out a geotechnical investigation for a mixed-use tower development in Rockdale, NSW. The proposed development involved the construction of two to six-level basement, which was to overly and be built around a major infrastructure tunnel which was to be protected during construction.
The investigation included drilling of cored boreholes, laboratory testing of collected soil and rock samples, and in-situ stress testing.
A Finite Element Analysis (FEA) using PLAXIS 3D, a three-dimensional FEA software, was completed to assess the potential movements and impact on the underground infrastructure by the proposed development. The results of the analysis helped assist the design of the basement excavation and its methodology, and allowed the development to progress past stringent council and infrastructure requirements.
