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 system increases the bearing capacity of concrete, reducing its deformation and cracking decreases, thus increasing its life.
该系统增加了混凝土的承载力，这样既减少其变形和开裂，也增加了混凝土的使用寿命。
