Model Test Of Rigid Composite Foundation Load Under Embankment

As the existing rigid composite foundation's research is mainly directed against the rigidfoundation to installed in the compound.Embankment Road will be applied, such as flexiblebasis composite foundation, which is calculated with the actual value often is a hugedifference.So on the basis of flexible composite mechanical properties and settlement of thefoundation's research is of great realistic significance.In this paper, lab tests,Analysis embankment reinforcement layer rigid pile CompositeFoundation under load analysis of the impact,come to a reinforced material stress and the axialforce of the pile, soil pile pressure pile-soil settlement, the influence of friction pile,Practice andcompared with some guidance.(1)Limiting the cushion to keep the level of sliding reinforced body, reducing the upwardpile "piercing" to increase the pile-soil stress ratio?Of the pile, reinforced the upwardtension in the body to reduce the weight of soil stress, and contrary to the top of thepile.The reinforced the downward pulling force have increased the weight pile loadit isadjusted to increase the load-sharing over the pile soil stress and load ratio? The role ofthe pile of reinforced body piercing progressive decrease, reducing the differentialsettlement of the pile and soil.(2)Under a formula drawn shaft axis,lateral friction along the pile length and depth underdifferent load stress changes in soil pile,Engineering Design of a certain significance.(3)Rigid foundation needs "soft cushion" and flexible foundation needs "rigid layer."Pile soillayer thickness of the stress ratio is too small, it is not advantageous for the soilbearingpiles, resulting in a waste of the project.Instead cushion cells, the need foradequate stiffness can give full play to the capacity figure.Subgrade cushion removed atany time in the conditions is the best way to regulate such contradictions within cushionreinforced.
