Breunese, J.N. van Thienen-Visser, K. de Waal, J.A. Publication year 2015 Abstract This paper presents a new formulation of the Rate Type Compaction Model (RTCM) for sandstone based on the isotach concept. The RTCM was originally developed to explain the loading rate dependent compaction behaviour observed in laboratory test on unconsolidated and consolidated sandstone samples and the delayed subsidence behaviour above depleting reservoirs. The original RTCM equation has the limitation of being unable to describe transitions between different loading rates, including the transition to a loading rate of zero (creep). The new formulation combines the features of the original RTCM with the isotach concept developed is soft soil geotechnics, which enables transitions between different loading rates, thereby overcoming the limitations of the original RTCM. The isotach formulation of the RTCM model is used to simulate a multiple loading rate experiment on a Rotliegend sandstonwe core sample. The agreement between results of the lab experiment and the proposed isotach RTCM model is excellent Subject Building Engineering & Civil EngineeringSD - Structural DynamicsTS - Technical SciencesBuildings and InfrastructuresMaterials2015 UrbanisationSandstoneCompactionCreepLoading rate dependentSubsidence delay To reference this document use: http://resolver.tudelft.nl/uuid:eef3ffd7-e2ca-4af0-bd65-00b1ad437412 TNO identifier 530040 Source International Journal of Rock Mechanics and Mining Sciences, 78, 127-132 Document type article Files To receive the publication files, please send an e-mail request to TNO Library.
