后压浆钻孔灌注桩单桩承载力试验研究

Bearing Capacity Trial Study of Single Stake Limitation of Post Motar Pouring

依据规范公式对2个工程实例的后压浆钻孔灌注桩的承载力进行了计算,并和静载试验结果进行了比较,比较结果表明,后压浆钻孔灌注桩的承载力有很大的提高.在对135根静载试桩分析的基础上提出了新的极限承载力计算公式,并通过数个后压浆钻孔灌注桩工程的实践,实践表明,其承载力计算结果与静载荷试验值比较吻合.

The bearing capacity is calculated after two pouring stakes in the drilled holes according to the regular formula in the real civil engineering.Compared to the trial result of the pure load it indicates that the bearing capacity after the poured stake enhanced on large scale.The author submitted the algorithm formula of new-limit bearing capacity after the experiment of 135 stakes load-bearing analysis.The result of bearing power algorithm is identical to the trial value of the quiet experiment.
