AbstractAt rest lateral stress in soils is an important parameter in geotechnical applications. In the past decades, much work has been done on the investigation of the lateral stress in sands. However, little information regarding lateral stress in cemented sands has been reported. -- This thesis presents the results of a laboratory study on the at rest lateral stress and coefficient of at rest lateral stress Ko of cemented sands. A state of the art literature review is presented, in order to provide a background to the static and dynamic behaviours of cemented sands. A modified oedometer ring was used to measure the at rest lateral stress in cemented and uncemented sands. Test materials were No. 3 Ottawa sand and a marine sand, and portland cement. The specimens were prepared by the method of undercompaction using 0, 0.5, 1.0, 2.0, 4.0 and 8.0% of cement by the weight of dry sand. The water content of the specimens was 4% of dry sand and cement. The test program was designed to investigate the influences of cement content, vertical stress, sand density, curing period and stress history. -- The test results indicate that the lateral stress in cemented sand decreases significantly with increasing cement content. The value of Ko increases with increasing vertical stress. The lateral stress decreases with increasing sand density and curing period. Stress history also has a significant influence on the behaviour of lateral stress in cemented sands.
