Rational and efficient ground investigations for industrialised construction of new railways

Purpose and goal:

The project aims to develop and test a methodology for rational preliminary studies for efficient industrialized construction of high-speed rail. This is done through a faster, simpler and cheaper methodology for producing a geological and geotechnical forecast that is sufficiently detailed to be able to begin environmental testing, cost calculation and risk assessment of the project.

The purpose is also to work with a process for structured management of all pre-investigation data in digital databases. Expected results and effects:

The forecast shall provide a basis for the planning and construction work aiming to select the right foundation class from a limited and standardized set. Parts of the improvement work are to compress the time for straw selection, general and detailed surveys. Furthermore, to minimize the time for field work through integrated and simultaneous surveys and avoid additional expenses through an automated, digitized and standardized approach.

Approach and implementation:

The track between Lund - Hässleholm is used as an application example. The project is divided into six work packages: 1. Integration of data in geodatabases with visualization tools; 2.

Engineering geological and geotechnical analysis and forecasting; Archaeological terrain analysis; 4. Drone-borne surveys; 5. Ground-based surveys; 6.

Analysis, evaluation and reporting. Within the framework of WP 1, which runs over almost the entire project period, deliveries are collected from e.g. WP 3, 4 and 5, which is then used in WP 2.
