高层建筑桩基础沉降预测

The Prediction of Settlement of Pile Foundation of High-rise Building

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,建立了高层建筑桩基础的龚帕兹沉降-时间预测模型,其中3个参数a、b和c可以简单求解得到。两个个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 high-rise building can be regarded as a linear loading process ; the theory results show that the s-t curve is S-shaped. According to the behavior of s-t curve, the Gompertz model is established to predict the ground settlement of pile foudnation. The three parameters in the model, a, b and c can be easily solved. This model is used to study 2 cases. The comparisons illustrate that the settlement predicted by Gompertz model keeps good agreements with the measured data.
