Accurate determination of soil stiffness at small strain (0.001 % -0.1 % strain) is very important as it portrayed the stiffness of soil underneath geotechnical structures. To evaluate stiffness at small strain, it is important to achieve a minimum strain measurement accuracy of 10-4 %, this is attained using transducers, strain gauges and sensors which are attached on the specimen locally inside the triaxial cell. Several local strains measuring techniques have emerged with the intention of developing a seamless system which is easy, accurate and less expensive. This study epitomizes the existing types of small strain measuring instrumentation, their trend of development and technology. Those that can measure both axial and radial strain, axial strain alone and radial strain alone are distinguished and described. Also, the accuracy, features, merits, and demerits of each type of device have been discussed accordingly. This paper provides information that enables selection of a suitable device that will best fit a particular application. It is anticipated that the study will inspire further researches in the area.

“…Equations presented in Rampello et al (1997) are here used to convert the shear wave velocity 3 data into small strain stiffness (Gmax -labelled as 'measured' on Fig 4f). More detailed account of these 4 equations is given in Likitlersuang et al (2013). As with the predicted Gmax values, preliminary estimates 5 of shear modulus at small strain are made as a function of the mean effective stress, drained shear 6 strength and void ratio, within a framework proposed in Bui (2009) for sand and clay.…”

11PTD, an acronym for Provenance -Transport -Deposition, is a multilayer geomorphotechnical system, the 12 combination of geomorphology, Quaternary Sciences, and geotechnical consequences of its 13 implementation in groundworks and other crosscutting disciplines. Embedded in its three layers are 14 geographical, geochemical, geophysical, mineralogy, dating, lithological and geotechnical inputs. In this 15 state-of-the-art review contribution and for Loess in England, Syngenetic and Epigenetic mechanisms are 16 drawn out and used to generate the three constitutive layers for three conceptual PTD models and the 17 interrelationships among them. The developed models are then deployed to inform earthworks design for 18 three HS2 embankments in Chiltern Hills. 19 20 21

Pipe-jacking is a construction method widely used in pipeline constructions. Prediction of ground deformation induced by pipe-jacking, is important for safety and scheduling purposes. This paper presents an approach to predict ground deformation during pipe-jacking considering following factors: (i) bulkhead additive thrust; (ii) friction on jacking machine; (iii) grouting pressure; and (iv) ground loss. Mindlin's solution was used to calculate the ground deformation induced by bulkhead additive thrust and friction on the jacking machine. The shearing disturbance coefficient was adopted to evaluate the mitigation effect of shearing behavior on ground deformation. Verruijt's solution was used to simulate the effect of grouting pressure. Sagaseta's method was adopted to consider the ground loss induced by over-excavation. Subsequently, a three-dimensional analytical solution for ground deformation induced by pipe-jacking was obtained. A case study based on a pipe-jacking project undertaken in Jiangsu, China was analyzed to validate the proposed approach. The results indicated that the proposed approach was robust and could be implemented for future pipe-jacking projects.
