The Geology-Engineering Partnership
Published in Aurèle Parriaux, Geology, 2018
“Engineering Geology is the science devoted to the investigation, study and solution of the engineering and environmental problems which may arise as the result of the interaction between geology and the works and activities of man as well as to the prediction of and the development of measures for prevention or remediation of geological hazards.

Ground investigation in glacial soils
Published in Barry G. Clarke, Engineering of Glacial Deposits, 2017
A ground investigation starts with a desk study, which includes studies of topographical, historical and geological maps, aerial photographs, geological memoirs and historical evidence of ground movement (BS5930:1999). The topographical, geological and engineering geology maps provide an indication of landforms, the generic geological profile and potential hazards (e.g. BGS, 2015). This is particularly important for some types of glacial soils, which can be intrinsically linked to the landform. The history of glacial soils, that is, the erosion, transport, deposition and deformation of a glacial deposit, and its impact on its geotechnical properties are difficult to assess from a desk study because of the nature and diversity of glacial soils, which makes it difficult to produce generic design parameters at this stage. However, an understanding of the formation of glacial soils and the landforms created provide a useful guide to what may be expected.

In 1997, Professor Wang Ren of Institute of Rock and Soil Mechanics, Chinese Academy of Sciences, published a monograph entitled “Coral Reef Engineering Geology of Nansha Islands,” which opened up the research field of coral reef engineering geology and physical and mechanical properties in China. Since then, geotechnical engineers and scientists in China have gradually increased their research on calcareous soils' unique physical and mechanical characteristics. In recent years, engineering accidents caused by insufficient understanding of the particular engineering properties of calcareous soil are still prevalent in coral reef areas globally. Severe damage to protective structures of the Maldives atoll coast caused by the Indian Ocean tsunami (Fujima et al. 2006) and a landslide event at Nice Airport in France (Dan, Sultan, and Savoye 2007) indicate that engineering problems caused by calcareous soil are not fully considered during planning and construction.
Horizontal and vertical motion at the surface of partially saturated soils layer sandwiched between water and elastic solid

Wave propagation studies at the water-ocean bottom interface are used to interpret the material properties of the ocean floor. The actual feedback about the ocean floor is investigated based on wave reflection signals. The study of seismic ground motion (horizontal and vertical motion) has significant consequences for assessing geo-acoustic properties of seabed sediments and their sub-bottom structure and the exploration of oil, gas, and water found in ocean floor rocks. Wave propagation at the ocean floor is crucial in many scientific domains, including seismology, engineering geology, hydrogeology, ocean engineering, and petroleum geophysics (both practically and theoretically). Hence, accurate modelling/study is required to investigate the various stages of oil, gases, and hydrocarbons embedded in the ocean floor.

In situations where a soil does not inherently display an adequate mechanical behaviour, enhancing its geotechnical properties is one of the most important measures that should to be taken into account. As a result, soil improvement by various materials and methods has been one of the most broadly discussed issues in the field of engineering geology and geotechnical engineering. Soil improvement techniques can be categorized into two broad groups of physical and chemical methods. Physical methods comprise dynamic compaction (Shen, Juang, and Chen 2019; Wu et al. 2020), preloading (Cai et al. 2017; Feng et al. 2017; Wang et al. 2019), explosive compaction (Daryaei and Eslami 2017; Esmaeili and Tavakoli 2019; Tavakoli and Esmaeili 2020), soil reinforcement (Saberian, Li, and Cameron 2019; Tavakoli Mehrjardi, Behrad, and Moghaddas Tafreshi 2019; Yang et al. 2020; Zheng et al. 2019), and using randomly distributed fibres as soil reinforcements (Abbaspour et al., 2020c; Mirzababaei et al. 2018a; Soltani, Deng, and Taheri 2018a; Yilmaz 2015) to name but a few. On the other, soil stabilization by materials such as cement, lime, fly ash, magnesium alkanization, rice husk, pond ash, natural pozzolans calcium carbide residue (Al-Swaidani, Hammoud, and Meziab 2016; Amini and Ghasemi 2019; Du et al. 2016; Gupta and Kumar 2017; Horpibulsuk et al. 2013; Jahandari et al. 2018; Muhammad, Siddiqua, and Latifi 2018; Muhammad and Siddiqua 2019; Siddiqua and Barreto 2018).
