摘　　要：静压预制桩具有无振动、无污染、造价低及质量可靠等优点。本文主要依据静力压桩与静力触探贯入相似的机理提出用静力触探指标预估压桩阻力的计算公式,并用杭州粉砂土地区的几个工程实例作分析和验证,为静压桩的设计和施工提供了理论依据。Static jacked precast piles have many advamages,such as no vibration,no pollution,lower price and better quality,etc.According to the fact that the penetrate mechanism of static sounding penetration and static jacking pile is similar,we obtained the predict formula of the static jacked resistance of the precast piles after comparing several engineerings,and can use it in the construction of the precast piles.

关 键 词：静压预制桩 静力触探 压桩阻力
