摘　　要：在试验基础上,分析夯实水泥土桩施工中负温和水泥土混合料放置时间对水泥土无侧限抗压强度的影响,证明夯实水泥土有较好的抗冻性,施工中应注意防止混合料受冻,还应严格控制桩体的夯实密实度。The captioned impact is analyzed based on test, which shows that rammed soil-cement has good frost resistance. In the construction attention should be paid to preventing the mixed materials from being frosted and strict control of the density of the rammed pile.

关 键 词：夯实水泥土桩 水泥土抗冻性能 无侧限抗压强度
