“…This form of adaptation is important, specifically in dealing with tidal effects on soil water content and soil temperature. Meanwhile, several studies showed that changes in soil temperature affect the bearing capacity of the pile foundation [10,11]. Gelam wood is a leading commodity and a potential source of local government revenue when managed properly.…”

Gelam wood (Melaleuca cajuputi Powell) is one of the essential raw materials for traditional foundations in Kalimantan, which is widely available along the wetlands. It plays an important role in supporting the construction of houses and other infrastructure in Indonesia. Consequently, there is a need for sustainable gelam wood cultivation in Kalimantan. Presently, it is not only used in the development of wetland stilt housing, but also for the interior of the house. Therefore, this study aimed to identify the pattern of using gelam wood as a foundation structure and its potential. The qualitative design method was used with an interview survey and literature review. The result showed that the patterns of using gelam wood as a foundation are as follows; 3-6 m length for simple buildings or 1-story houses, 7-10 m length for 2-story buildings or highrise buildings, and 3-4 m length for road construction. The diameter of gelam wood used varies between 8-15 cm. Furthermore, the potential use is very large, where the need for residential foundations in Banjarmasin City is approximately 30000 m 3 in 1 year, and an average of 14000-20000 are needed for 1 road construction project, not including those used for other structures.

“…The influence of temperature on the UBC of pipe piles cannot be ignored [28,29]. Based on the finite element model described in Section 4.1, a thermal load is applied on the pile surface and soil surface to transfer the temperature along the depth of the soil to study the variation in the pipe pile bearing capacity under the action of temperature.…”

Prestressed high-strength concrete (PHC) pipe piles have been widely used in engineering fields in recent years; however, the influencing factors of their ultimate bearing capacity (UBC) in multilayer soil need to be further studied. In this paper, a static load test (SLT) and numerical analysis are performed to obtain the load transfer and key UBC factors of pipe piles. The results show that the UBC of the test pile is mainly provided by the pile shaft resistance (PSR), but the pile tip resistance (PTR) cannot be ignored. Many factors can change the UBC of pipe piles, but their effects are different. The UBC of the pipe pile is linearly related to the friction coefficient and the outer-to-inner diameter ratio. Changes in the pile length make the UBC increase sharply. Low temperatures can produce freezing stress at the pile–soil interface. The effect of changing the Young modulus of pile tip soil is relatively small.

“…Clay is a finely grained material from natural rock and soil that consist of minerals such as hydrous aluminum and little traces of quartz, metal oxides and organic matter. The major content of geologic clay deposits is phyllosilicate minerals, which contain variable amounts of water found in its mineral structure [7,8]. The clay material used for the present study comes from the small city of Jingdezhen, Jiang Xi province, South East China.…”

The Influence of Clay-Like Materials Plasticity Used as Infills, on Jointed Rocks Mechanical Behavior

The Rock mass is often described as an anisotropic material with several discontinuities within its structure ranging from joints, bedding plans to faulting. In the present study, the effects of infills plasticity on rock mass behavior during failure were investigated. Thus, a series of experiments have been conducted on both soils and cement blocks reconstituted to reflect jointed rock behavior. Different soil materials (obtained by mixing clay and sand) were subject to the cone penetration test and the unconsolidated undrained triaxial test to determine their plasticity index and their unconfined compressive strength. Then, several jointed blocks using the aforementioned soil materials as infill were subject to a uniaxial compression test to assess their maximum stress and investigate their deformation and failure mode. Results showed that stiffer infills would induce a more brittle behavior in the jointed rock while softer infills would instead favor rock deformation and a sharp decrease of its strength. It was also observed that both infill' cross-section and thickness will affect the rock resistance but its deformation will largely be influenced by the later. In the end, some law equations were proposed to draw the mathematical relationship between the jointed rock maximum stress, its deformation at failure and the infill plasticity.
