Investigation on Static Stability of Sheet Pile Quay Wall Improved by Cement Treated Sea-Side Ground from Centrifuge Model Tests

Behavior of Sheet Pile Quay Wall Stabilized by Sea-Side Ground Improvement in Dynamic Centrifuge Tests

“…3. As similar to the static loading tests (Khan et al, 2008), it can be concluded that the diŠerence in the strength of CDM is negligible on the seismic behavior of improved ground.…”

“…This method has been introduced by Khan et al (2008) in the static investigation. Elastic equilibrium of forces acting on the horizontal slice of sub-divided layers below the ground level is considered.…”

“…The measured bending strain along the sheet pile wall isˆtted by quantic spline functions, and the de‰ec-tion distribution and the subgrade reaction distribution are calculated by two successive integrations and diŠeren-tiations respectively. The ks value for each layer is calculated by the de‰ection and subgrade reaction distributions according to the method presented by Khan et al (2008). In the previous research, the measured bending strain along the sheet pile wall subjected to the static loading wasˆtted by quantic spline functions, and the de‰ection distribution and the subgrade reaction distribution were calculated by two successive integrations and diŠerentiations respectively.…”

“…Sea-side ground improvement is one of the techniques which will not interrupt the port-side activities during its execution. The static behavior of the sea-side ground improved with cement deep mixing (CDM) (CDIT, 2002) was studied by Khan et al (2008) through a series of centrifuge model tests. Results of the study indicated that the improved ground provided signiˆcant resistance against static horizontal load increment.…”

Contributions to “Soils and Foundations”: Ground Improvement

“…They found that the failure of the wall took place suddenly without marked pre-failure soil and wall movements and found that the stability was in‰uenced by the dimension of the wall and the soil properties of the surrounding clay ground. Recently Khan et al (2008Khan et al ( , 2009) carried out static and dynamic centrifuge model tests on a sheet pile quay wall stabilized by stabilized soil and proposed a design method for the dimension of a stabilized soil block based on the soil reaction theory. In a study on internal stability, Kitazume (1998) carried out a series of centrifuge model tests on the failure behavior of stabilized soil mass, and found that the failure behavior was characterized by vertical tension cracks and shear failure, which was diŠerent from that of clay and sand ground.…”
