深厚软土层中桩基础的长期沉降预测

摘要

According to the settlement data from the experimental field,the paper established models by using the hyperbola method,the index curve method,BP neutral network method,and the gray system theory,predicts the long-time settlement tendency and the final settlement value of the pile foundations in the deep soft soil layer,and solves the factual engineering problems,and provides the theoretic reference and technical support to the engineering construction.%根据试验现场实测沉降数据,分别利用双曲线法、指数曲线法、BP神经网络法和灰色系统理论法进行建模,对深厚软土层中桩基础的长期沉降趋势和最终沉降值进行预测,解决了实际工程问题,并为工程建设提供了理论依据和技术支持。
