Approximately 25% of China's 120 000 km expressway, as well many new metro lines and airports, rest on soft clay deposits. However, service settlements are proving larger than expected, especially in southeast China. This note describes laboratory experiments K 0 -consolidated intact samples taken near Wenzhou, south-east China, that explore whether cyclic traffic wheel loading contributes significantly to the observed settlement trends. Cyclic triaxial (CT) tests reported together with...
Vehicle traffic loading appears to contribute significantly long-term settlement beneath highways, airport runways, and metro lines in China. Wheel imposes cycles both the magnitude direction of principal stresses acting on soils pavement or rail-track structures. Conventional cyclic triaxial (CT) testing, which is not capable imposing such stress paths, may underestimate how heavy affects any underlying soft clay layers. A hollow cylinder apparatus (HCA) can simulate paths more accurately,...
The loading path involving principal stress rotation (PSR) during shear is an important phenomenon encountered in many field conditions. Typically for traffic loading, both the magnitude and direction of stresses may vary with time due to motion vehicles, can be mimicked by a heart shape deviatoric space. Conventional triaxial tests are not suitable recreate this type that no torsional applied on test samples. To overcome limitation, series using hollow cylinder apparatus were conducted sand...
In certain field conditions, the soil element is subjected to cyclic stress paths with both principal rotation and deviatoric variation. To better understand response of soft clay under this type path, 19 tests were conducted on undisturbed Wenzhou through hollow cylinder apparatus. By using defined waveforms, a series experiments that mimic cardioid-shaped carried out different axial shear levels. The development strain, stress-strain relationship, dynamic modulus are discussed. Results...
A series of drained tests were conducted on the medium dense Toyoura standard sands using a hollow cylinder apparatus, including both F (sheared with fixed principal stress direction) and R constant deviatoric but rotating directions). The effects anisotropy deformation characteristics examined, inherent that formed in process sand sample preparation which induced due to 'inclined' consolidation. results showed effect was significant stress–strain behaviour failure strength sand. It also...
Drained torsional shear tests were performed on hollow cylindrical intact soft clay specimens to investigate the anisotropic deformation, strength, and noncoaxial behavior in general stress states involving variations both magnitude direction of principal stresses. Tests conducted by maintaining a fixed α relative vertical while keeping intermediate coefficient b constant. It was found that magnitudes radial strain εr dependent value, circumferential εθ angle. The influence relationship...
The deformation behavior and shear strength of soft marine clays subjected to wave or traffic loads are different from that in triaxial loading due the changes major principal stress direction β intermediate coefficient b. To investigate anisotropy affected by b natural clay, a series drained tests were conducted hollow cylinder apparatus. relative vertical maintained constant under an increasing stress, with fixed influence on typically Wenzhou intact clay is discussed. It was found...
During embankment construction, the deformation behavior of soil will vary with increasing fill height because principal stresses applied on elements in K0-consolidated subsoil rotate. In this study, a series tests is conducted natural Wenzhou soft clay hollow cylinder apparatus (HCA) to clarify response soils during stress rotation. Specimens are sheared different angles inclination (β) respect vertical direction undrained conditions. The stress-strain relationship, pore-water pressure...
