Safety and quality assurance for geotechnical constructions in urban areas

Abstract

Safety and quality assurance are the most important aspects for the design and the construction of geotechnical structures. These aspects consider the optimisation by reducing the resources material, money and time. For construction projects with a distinctive soil-structure interaction in the vicinity of existing structures special methods have to be applied to guarantee safety and quality. Therefor numerical simulations using the Finite-Element-Method (FEM), in-situ load tests on the construction site, special foundation techniques like the Combined Pile-Raft Foundation (CPRF), the observational method and an independent peer review are necessary. The paper explains the application and the combination of these tools by examples from engineering practice.
