Loading Capacity

A new chelating resin was prepared by mixing sulfadiazine drug and TMP (trimethylolphenol). It was polymerized by heating to 90°C then it was post cured to 100°C after that it was grinded. The chelating behavior was examined against Cu2+, Ni2+using patch method in deferent conditions like treatment time and pH at room temperature. The resin show a good loading capacity toward Cu2+(in treatment time = 3 h & pH=4) = 0.2174 mg ion / 100 mg resin and it show good loading capacity toward Ni2+(in treatment time = 24 h & pH=4) = 0.14 mg ion / 100 mg resin.

Centrifuge Model Tests

Plate anchors have attracted much attention in offshore deep water development. This paper studies anchor rotation and chain reaction during plate anchor inclined pullout when it is installed vertically in clay. Both numerical simulation of strip plate anchor and centrifuge model tests on square anchor are conducted in uniform and normally consolidated (NC) clay. In the numerical analysis, Remeshing and Interpolation Technique with Small Strain model (RITSS) is used to simulate large movements of the anchor. In the centrifuge model tests, a transparent “soil” is used to observe anchor rotation and chain reaction during anchor pullout. It is found that plate anchors reach ultimate capacity (Nc ≈ 11.7) when they are fully rotated to a position perpendicular to the pullout direction. During anchor pullout at 60° to the horizontal, the loss of embedment during keying-in ranges from 0.38 B to 0.58 B for square and strip anchors in uniform and NC soils. The loss of anchor embedment in NC clay is about 4% ∼ 23% higher than that in uniform clay depending on the soil strength profile in the NC soil.

Plate Anchors

Plate anchor is one of the most popular types of anchors widely used in geotechnical engineering. Reliable prediction of the ultimate uplift resistance of plate anchors requires its failure modes well understood. In this paper, an image-based deformation technique, the digital image cross-correlation (DIC), is used to measure the sand deformations around a scaled semi-circular anchor during uplifting. A series of tests have been conducted to investigate the failure modes of plate anchors in both loose and dense sand. Two distinctively different failure modes are measured by using DIC in both loose and dense sand respectively. This model study improves the understanding of the failure and development of loading capacity of uplift anchor in cohesionless soil.
