The Design Theory And Application Of Piles Foundation Counterfort Retaining Wall

The structure of piles foundation counterfort retaining wall is generally appliedin fill slopes．When the capacity of retaining wall foundation is low, the pilesfoundation is always used. the piles foundation can not only enhance the capacity ofretaining wall foundation, but also resist landslide thrust. Though the structure iswidely used, the present design theory is not very effective. Therefore, to strengthenthe design theory of piles foundation counterfort retaining wall is important andvaluableBased on the Zhong Ye Yu Luan Wan counterfort retaining wall project, Thisdissertation analysis the force of structure, expounds the present design theory, andput forward the new design theory. The main research contents of this dissertation areas follows:．（1）This dissertation discussed the force on the structure and how to calculatethe earth pressure and landslide thrust.（2）According to the stress characteristics of pile foundation supporting wallstructure, presents the calculation model of rotary pile wall retaining wall．（3）The author consider that: the double row piles foundation counterfortretaining can be simplified as a "∏" structure, and then, use the structure mechanicstheory to calculate the internal force.（4）Use the Phase2D numerical analysis software to analysis the pile foundationcounterfort retaining wall structure. Based on the Zhong Ye Yu Luan Wancounterfort retaining wall project, the numerical analysis model is built, and thenumerical analysis results can be gained.
