Single pipe pile shows sliding failure at interface and cannot utilize the strength of material; the bearing capacity and deformation ability are low.
结果表明，现行的单钢管桩属于界面的粘结破坏，承载力低，变形能力弱，不能充分发挥材料特性。

The test result show that BGB plastic cushion material can restrict the tensile stress and strain and prevent the facing from crack under a relatively small sliding displacement.
The result shows that the compound material bearing surpass the 20 high tin sliding bearing in endurance to pressure, adaption to variable temperatures and life for use and so on.
