Fractional order creep model for coral sand

Mechanics of Time-Dependent Materials, 2018
The creep of coral sand is a critical factor that needs to be considered in geotechnical design of engineering facilities along coastal areas. In this study, a new fractional order creep model for coral sand is developed by extending the previous work on fractional (visco)plasticity.

Variation of Wind Resistance Reliability of Foundation in Coral Sands

Advanced Materials Research, 2013
Considering variation of bearing capacity of foundation caused by crushing of coral sands, the variation of wind resistance reliability of foundation in coral sands was studied. Based on the use of exponential decay model of bearing capacity of foundation, the reliability index of foundation at different time was calculated.

Effects of sand deposition on scleractinian and alcyonacean corals

Marine Biology, 1995
The ability of corals to withstand experimental sand deposition was investigated for two experimental periods (17 h and 6 wk) in eight scleractinia (Favia favus, Favites pentagona, Platygyra daedalea, Gyrosmilia interrupta, Galaxea fascicularis, Cyphastrea chalcidicum, Favites abdita, Goniopora dijboutensis) and five alcyonacea (Lobophytum depressum, L.

Settlement Reliability Analysis of Gravity Foundation in Coral Sands

2011 International Conference on Computational and Information Sciences, 2011
Settlement calculation is an important work in design of foundation of building structure. In this paper, the reliability method is used to analyze the settlement of gravity foundation in coral sands. By calculating settlement using secant modulus method, performance function of settlement reliability analysis of foundation is established. JC method is

Comparative study on seismic response of a shallow buried underground structure in coral sand and coral gravelly sand by centrifuge modeling

Tunnelling and Underground Space Technology
Coral sand, as a geological material for foundation filling, is widely used for reclamation projects in coral reef areas. The coral sand is characterized by a wide grain size distribution. A series of centrifuge shaking table tests were conducted to explore the seismic response of a shallow buried underground structure in saturated coral sand and coral

Strain rate-dependent undrained response of a coral sand

Géotechnique Letters
The strain rate-dependent response of sand is influenced by particle crushing. However, such a conclusion is drawn in the previous studies, primarily based on drained triaxial or 1D compression tests on crushable sand. This study explores the interplay of strain rate and crushing behaviour of sand under undrained triaxial (CU) conditions.

Calcareous Sands from a Coral Atoll-Should It Be Mined or Not?

Marine Georesources & Geotechnology, 1999
Many lagoons of coral atolls contain huge reserves of very pure calcareous sands in an easily exploitable form that can be used in a number of industries. It is well known that the geomorphic situation in these coral islands is very delicate. With reference to the calcareous sand deposits in the coral atolls of Lakshadweep, a diversity of opinion ...
