| 摘 要： | 我国目前桩基设计规范对压桩施工过程中的桩身结构强度验算,尚未做出明确的规定,本文围绕这一问题讨论了以下问题:(1)进入持力层不同深度对压桩阻力的影响;(2)用静力触探比贯入阻力预估压桩阻力;(3)压桩施工过程中桩身结构强度的验算。

| Abstract: | The checking computation of pile structural strength of statically jacked pile during its installation is not explicitly established in the codes of pile foundation design.In this paper the following issues are discussed:(1) the relationship between the sinking-pile resistance and the pile tip depth in the bearing layer;(2) the estimation of sinking-pile resistance from the specific penetration resistance of static penetration test;(3) the checking computation of pile structural strength of static-press pile in the process of installation. |
