Abstract:

The viewpoint that earth pressure acted on breast board is lesser when flexiboard is used in sheet-pile wall engineering, which is expounded based on the load distribution and deforming characteristic of board between two adjacent piles. There are some problems which exist in simplified granary method and unloading-arch theory; therefore, the model tests for simulating the flexiboard sheet-pile walls used in reinforced fill foundation on ramp are designed to primarily research and compare earth pressure distribution patterns when flexiboards are fixed on frontal or dorsal suiface of piles. It is indicated that both of earth pressure acted on flexiboards and their deflection deformations are lesser; moreover , soil arching effect is more intensive, when the flexiboards are constructed on the frontal surface of piles according to testing results of dial indicators and earth pressure cells. The measured soil pressure distributions of flexiboards almost present parabolic curves, whereas dorsal load ditributions of piles are complex. In addition, the comparison and analysis are made about two theoretical calculation values and testing results. Finally, the time effect of earth pressure variation is studied by monitoring earth pressure cells when flexiboard is on the dorsal suiface of piles; this process that has been lasting for 21 days since boulder strips had been stacked on fill foundation.

Key words: flexiboard, sheet-pile wall, fill foundation, earth pressure cell, time effect
