...Alejandra López Ramírez; Yinning Zhang; Juha Forsman; Leena Korkiala-Tanttu Dry deep mixing (DDM) is a soil stabilization method widely used in countries with large soft clay areas, such as in the Nordic countries. In Finland, DDM is performed using a binder material that commonly consists...

...Sølve Hov; Fredrik Falle; Priscilla Paniagua The dry deep mixing method is a widely used stabilization method in the Nordic countries to improve the strength and deformation properties of soft clays. In engineering practice, laboratory tests normally precede in situ stabilization; however, previous...

...Ismaail Ghaaowd; John S. McCartney This paper describes a test setup and methodology for centrifuge modeling of energy pile pullout from saturated soft clay, with the goal of understanding how pile heating improves the interface shear strength through thermal consolidation. A kaolinite clay layer...

... with the presence of a soft, weak layer employing centrifuge testing. The model consisted of a three-layered slope of relatively soft clay with a 3° inclination, representative of Brazilian marine subsoils. In-flight characterization of the undrained shear strength and shear wave velocity profiles were achieved...

...Haibo Wang; Changtai Zhou; Jingyu Ji To investigate the thermal effect on soft clay, a novel local temperature-controlled device is presented based on an advanced dynamic triaxial testing system. Then, a calibration study is carried out to verify the robustness and effectiveness of the designed...

... phyllosilicate (MLPS). The effect of aging on the shear strength of transparent soft clay formed from MLPS and water is presented in this article. A miniature ball penetrometer (MBP) was developed for this study. MBP tests were used to measure the shear strength of samples at three different concentrations...

...Helene Alexandra Amundsen; Vikas Thakur The effects of storage duration on the sample quality of 54-mm piston samples were investigated by an extensive laboratory study. A soft clay deposit in Central Norway was used as a research site—the Tiller site. The soft clay deposit consists of two types...

...Nihat Dipova In standard unconfined strength testing, only the axial strain is measured directly, and the radial strain is calculated based on the assumption of uniform deformation. Alternatively, there are other assumptions, such as parabola and conical frustum. In fact, soft clays lose cylinder...

... engineering community over several decades. However, in the case of soft to very soft clays, the correlation between the standard penetration number ( N ) and the undrained shear strength is poor. In the recent past, tests conducted at a constant rate of penetration, such as the cone penetration test (CPT...

...H. Zou; G. Cai; T. V. Bheemasetti; S. Liu; A. J. Puppala Uncertainty evolved through in situ testing, such as measurement error, is a major concern in the characterization of soft clays that suffer from the low strength and high sensitivity of soil properties. In this research, 20 piezocone...

...Zhou Jian; Xu Changjie The effect of shear stress on strain development and pore water accumulation resulting from principal stress rotation tests on intact Hangzhou soft clay using a Zhejiang University hollow cylinder apparatus (ZJU-HCA) is reported. Different types of tests were designated...

.... The spacing between all the holes equals twice the stone column diameter, D , center to center. The stone columns made of crushed stone were installed in very soft clays having undrained shear strength ranging between 6 and 12 kPa. Two length to diameter ratios L / D were tried, namely, L / D =6 and 8...
