摘　　要：针对预应力高强空心桩(管桩和方桩)工程应用进行分析。结果表明:在用材相当的情况下,预应力高强管桩的性能较预应力高强空心方桩的优越;预应力高强管桩可以适用于抗震设防区;预应力高强空心桩可以作为抗拔桩使用。同时对预应力高强空心桩提出了实际应用中的一些注意事项。The applications of prestressed high-strength pipe piles and prestressed high-strength hollow square piles were discussed. Conclusions are obtained that the performance of prestressed high-strength pipe piles is superior to that of prestressed high-strength hollow square piles when the material usage is equal. Prestressed high-strength pipe piles can be applied in seismic zone, and prestressed high-strength pipe piles and prestressed high-strength hollow square piles can be used as uplift piles. Several suggestions were given in the applications of prestressed high-strength pipe piles and prestressed high-strength hollow square piles.
