试验研究了常压蒸养护和高压蒸汽养护工艺生产的预应力高强度混凝土管桩混凝土的脆性和耐久性。研究结果表明，常压蒸养预应力高强度混凝土管桩混凝土的脆性小于高压蒸养混凝土；常压蒸养预应力高强度混凝土管桩混凝土抗氯盐侵蚀性能和抗冻性等耐久性高于高压蒸养混凝土。采用常压蒸养生产预应力高强度混凝土管桩有利于预应力高强度混凝土管桩的抗锤击性能，适用于北方冻融和海洋环境。
試驗研究瞭常壓蒸養護和高壓蒸汽養護工藝生產的預應力高彊度混凝土管樁混凝土的脆性和耐久性。研究結果錶明，常壓蒸養預應力高彊度混凝土管樁混凝土的脆性小于高壓蒸養混凝土；常壓蒸養預應力高彊度混凝土管樁混凝土抗氯鹽侵蝕性能和抗凍性等耐久性高于高壓蒸養混凝土。採用常壓蒸養生產預應力高彊度混凝土管樁有利于預應力高彊度混凝土管樁的抗錘擊性能，適用于北方凍融和海洋環境。

The brittleness and durability of prestress high concrete pipe piles on non-steam autoclaved and steam autoclaved were exper-imentally studied.Experimental results showed that the brittleness of non-steam autoclaved concrete was less than steam autoclaved con-crete's.Moreover,the chlorine-resistant and frost-resistance properties of non-steam autoclaved concrete were better than steam autoclaved concrete's.prestress high concrete pipe piles on non-steam autoclaved excels in anti hammer ,it was applicable in freeze-thaw and chlorine circumstance.
