桩基础沉降预测分析

Settlement prediction of pile foundation

高层建筑施工过程可近似地看为一个线性加载的过程,在沉降—时间曲线特征的基础上,建立了桩基础的龚帕兹沉降—时间预测模型,工程实例的应用证明了该模型在桩基沉降预测中的合理性和实用性。

The construction of building can be regarded as a linear loading process. According to the behavior of s-t curve, the Gompertz model is established to predict the ground settlement of pile foudnation. This model is used to study two cases. The comparisons illustrate that the settlement predicted by Gompertz model keeps good agreements with the measured data.
