【摘要】 通过分析某粉土地层中预制桩静压沉桩的相关数据,得出沉桩压力上限与双桥静力触探探头阻力之间的关系,认为粉土地层中由JGJ 94—2008《建筑桩基技术规范》式5.3.4计算的单桩竖向承载力标准值与沉桩压力相近,进而找出极限端阻力标准值与桩基压桩力、以及与压桩力分配在桩端的压力之间的上限关系.更多还原

【Abstract】 Through analyzing the relevant data of statically pressed precast in silt layer,we got the correlation between the upper limit of static pressure pile and probe resistance of double-bridge CPT,which provides a reference for similar projects.We also find that the standard value of single pile vertical bearing capacity calculated according to equation 5.3.4 from Construction of Pile Foundation Technical Specifications(JGJ 94—2008)is similar to that of the static pressure pile in silt layer.The correlation between the upper limit values of pile foundation pressure and the single pile vertical bearing capacity is analyzed.更多还原
