摘要
桩基承载力对桩基抗震性能有很大影响。介绍了一种单桩静载荷试验极限承载力的预测法——多项式回归法。在静载荷试验中,由于种种原因终止荷载未达到极限荷载时,可用上述方法进行推测。同时通过实例对比说明,这种方法对于静载荷试验具有一定的经济效益。
Bearing capacity of pile foundation has a big influence on anti-earthquake capacity of pile foundation.In this paper, a method, called multinomial regression for forecasting for ultimate bearing capacity of singe pile with static load experiment is proposed. In a static load experiment, such a method can be used to make estimation in the case that exerted final load can is not up to ultimate bearing capacity. The practical comparison shows that this method can reduce cost of static load experiment.
