Application of expanded polystyrene (EPS) geofoam and deep cement mixed columns for protection of existing foundations during urban construction

澳大利亚首府城市建设活动日益增多，现有建筑附近的新建筑活动也越来越多。该项目的主要成果将为在城市建设活动中保护建筑物提供经济的工程战略，从而将最近悉尼Lane Cove隧道坍塌事件中与建筑相关的损害、诉讼和延误降至最低。提出的使用EPS地泡沫和深层水泥搅拌的新型解决方案将显著提高澳大利亚建筑业的国际竞争力和出口潜力，并增强社区对开发商和工程专业的信心。

Urban construction activities are increasing in the capital cities of Australia, and the occurrence of new construction activities near existing structures is increasing. The main outcome of this project will provide economic engineering strategies for the protection of buildings during urban construction activities, hence minimising construction related damage, litigation and delays as witnessed recently during Sydney's Lane Cove tunnel collapse. Proposed novel solutions using EPS geofoam and deep cement mixing will significantly increase the international competitiveness and export potential of the Australian construction industry, and improve community confidence in developers and the Engineering profession.
