Mechanism of sheet-pile wharf with barrier piles
摘要
Abstract
The main problem for deep-water sheet-pile wharf is how to deal with the earth pressures acting on the front wall, which dramatically increase with the excavation depth. The design idea of the barrier-pile structure is as follows: a row of barrier piles are constructed in front of the traditional sheep-pile wharf, and part of the earth pressures acting on the front wall are shared owing to their barrio effects so as to reach the condition for building large deep-water sheet-pile wharf. Using the developed analysis software for soil-structure interaction based on ABAQUS, the NHRI double-yield face elastoplastic constitutive model is employed to simulate stress-strain relation of soils. The constitutive model based on contact mechanics is used to simulate soil-wharf interaction. The mechanism and effect of barrier piles are studied, the distribution rules of earth pressures at the two sides of the front wall of the sheet-pile wharf with barrier piles are discussed as well as its deformation and distribution of bending moment. By comparing with the sheet-pile wharf with single anchorage, the deep-water sheet-pile wharf with barrier piles is validated.关键词
