Some fracture theories of materials with large deformation have ever been elucidated by Wong and Shield[2], Knowles and Sternberg[3], and Geubelle[4], who aimed at clarifying the asymptotic structure of the deformation theoretically.

Based on this thought, the Union House, which is the first flexible pile isolation structure in the world, was constructed in New Zealand in 1983(Boardman et al 1983), and it works normally up to now When the bending spring of EDIPF is failure during a massive earthquake, the pile may also have a large horizontal deformation, which can bring about a collision between the pile and the pile sleeve, and sometimes, the active control is applied on EDIPF to form a hybrid control system to avoid this collision.There are many researches(Cai et al 2002;Wong et al 2008;Sun et al 2008;Huang et al 2009) for hybrid control of traditional isolations, but no work for control of EDIPF was reported up to now.
