夹桩时预制桩的强度分析

Analysis on the Strength of Pre-Fabricated Pile under Pile Clamping

对夹桩时夹桩机构和预制桩的静态受力进行了分析,结论表明:夹桩时预制桩的屈服从与下钳口接触处的内壁开始;预制桩能承受的最大夹桩力随着夹桩钳口与预制桩之间的接触长度、预制桩的外径和壁厚的增大而增大。

An analysis of the static forces of pile clamping mechanism and pre-fabricated pile under pile clamping was carried out.The results reveal that the yield of pre-fabricated pile under pile clamping starts from the inner wall contacting with the lower jaw;the sustainable pile clamping force of pre-fabricated pile under pile clamping increases with adding properly contact length between pile clamping jaw and pre-fabricated pile and with augmenting becomingly the outside diameter and wall thickness of pre-fabricated pile.
