Innovation and Sustainability in Geotechnics for Developing Africa

Hosted in one of the continent’s most iconic cities, this conference will serve practitioners, academics and students of all geotechnical backgrounds. The conference will offer extensive opportunities for technical committee meetings, workshops, paper presentations, exhibitions and sponsorships. A variety of tours, including to famous Robben Island, await.

Developments in unsaturated soil mechanics, which are of special relevance in the African context, will feature prominently at the conference. The conference will host the 17th Jennings Lecture presented by world renowned unsaturated soils expert Prof Delwyn Fredlund (Canada). In addition, a course on unsaturated soil mechanics by Prof David Toll, Prof Antonio Gens, Prof Charles Ng and Prof Samuel Ampadu will be presented. Further theme lectures by Prof Buddhima Indraratna (Australia) and Dr. John Mukabi (Kenya) will be presented. The conference is also proud to host The International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) Board and Council meetings preceding the main event. Furthermore, the International Geosynthetics Society (IGS) will be hosting their board meeting during this time as well.

The 7th African Young Geotechnical Engineers Conference (AYGEC) will commence on Sunday
6 October, preceding the African Regional Conference. The AYGEC conference will offer an ideal opportunity for young geotechnical practitioners to interact and present their work on a continental platform. The program has been tailored to encourage young geotechnical practitioners to attend the pre-conference courses and stay on for the main conference.

Liquefaction-Induced Settlement of Structures on Shallow Foundation

By C.W. Lu, L. Ge, M.C. Chu, and C.T. Chin

ABSTRACT: Unlike the liquefaction potential assessment, the liquefaction-induced ground settlement has not been studied extensively. The uncertainty of the ground profile and associated soil engineering properties is the major challenging to advance the current knowledge on this subject. Within Ishihara and his colleagues’ framework, the liquefaction-induced settlement is computed by the associated post-liquefaction volumetric strain, once the factor of safety for liquefaction is evaluated. For estimating settlement of a building with shallow foundation in liquefiable soils, on the other hand, dynamic behavior of the soils, its relative density, and the thickness of liquefiable soil, building’s weight and dimensions, seismic intensity, and structure-soil interaction should be considered accordingly. This paper aims to develop a practical and simple procedure to estimate the liquefaction-induced settlement on structures on shallow foundation, based on the framework proposed by Sawicki and Mierczynski in 2009. A series of comprehensive numerical analyses were carried out to incorporate the above-mentioned factors in the developed procedure. Data of liquefaction-induced settlement of structures on shallow foundation reported in the literature were used to compared with the estimated ones.

Trenchless Excavations for Underground Pipelines in Difficult Geology

By Keh-Jian Shou, Jonas Yen, and Chih-Ying Hsieh

ABSTRACT: No-Dig constructions in the city might encounter various difficulties. And the difficulties or obstacles, which might cause schedule delays and damage to the pipes. Among the others, the conditions of overcut and stuck could be the most common and critical to a pipejacking project. This study considered various difficult conditions, including different overcut range and sticking position, together with different resistance, jacking force, etc. The ABAQUS finite element software was applied for three-dimensional numerical simulations for pipe-jacking with different difficult situations. The analyses focused on the pipejacking in gravel formations, and the suggestions were concluded based on the results. The results suggest that the location of sticking and its severity (different frictional coefficient was set) affect the stress field in the pipe. And the worst condition, i.e., the totally stuck, the adjacent soil and pipe will experience excessive deformation, which must be avoided. Therefore, lubrication to avoid this extreme scenario is essential in the pipejacking operation. For the case with large diameter, unavoidable overcut and highly variable geology, the above suggestions are more crucial.

Hexagonal Wire Mesh Panel Tensile Behaviour due to Weaving Patterns

By Chiwan Hsieh, Zhi-Yao Cai, and Wen-Shin Shuy

ABSTRACT: The tensile engineering properties of a commonly used wire mesh (120mm x150mm, ψ=4.0mm) with triple-twist (Type A) and fourth-twist (Type B) weaving methods according to the ASTM A975 test standard are studied. Wire mesh panel tensile tests loaded in the longitudinal and transverse directions with and without centre cut wire conditions and panel connection to selvedge tests were evaluated. Generally, the longitudinal tensile strengths were higher than that for the transverse tensile strengths. The Type B panel longitudinal and transverse direction tensile strengths and connection to selvedge strengths were all greater than those for Type A panel. In addition, the Type B panel showed better strength retention rates than the Type A panel with and without centre cut wire condition. The Type B panel showed better tensile behaviour than the Type A panel.

Validation of a New Simplified Hypothesis B Method for Calculating Consolidation Settlement of Clayey Soils Exhibiting Creep

By J.-H. Yin and W.-Q. Feng

ABSTRACT: This paper introduces a new simplified Hypothesis B method for calculating consolidation settlement of clayey soils exhibiting creep. The general equations of the new simplified Hypothesis B method are presented and explained firstly. After this, four different cases are used to examine the validation of this new method. The four cases are: (i) a single layer of clay with laboratory test data, (ii) one layer of Hong Kong Marine Deposits (HKMD) with three different over-consolidation ratios (OCRs), (iii) one layer of HKMD with vertical drain, and (iv) two layers of HKMD and Alluvium. The fully coupled consolidation analyses of all four cases are done by using one commercial FE program using a soft soil model, one in-house developed FE program and a finite difference method using Yin and Graham’s Elastic Visco-Plastic (EVP) model. The consolidated settlements of the same cases are also calculated using the new simplified Hypothesis B method and Hypothesis A method and are compared with values from numerical methods. The relative errors are calculated by using the FE results as reference. It is, from the above validation cases, found that the settlements calculated using the new simplified Hypothesis B method are closer to test data or the values from the fully coupled finite element (or finite difference) analyses with the least relative errors. Hypothesis A normally under-estimates the settlement a lot with the largest errors. The main conclusion is that the new simplified Hypothesis B method is very suitable for calculating consolidation settlement of clayey soils exhibiting creep and is easy to use by simple spreadsheet calculation.
