基于新建承德机场沉降量的实测资料,针对西端高边坡的地基沉降问题,采用指数曲线函数模型和双曲线函数模型以及皮尔曲线模型进行了最终沉降量预测。对比分析了不同数学模型的拟合精度,通过对不同模型拟合效果的比较,选取双曲线模型对承德机场工后最终沉降量进行预测,得出新建承德机场西端高边坡测点1-4的最终沉降量为58.24mm。最终沉降量的预测结果对机场后续监测和建设具有指导意义,对机场后续工程起到优化施工和安全预报的作用。
Based on the measured data of the settlement of the newly built Chengde Airport, the ultimate settlement is predicted by the exponential curve function model, the hyperbolic function model and the Peel curve model. Comparing the fitting accuracy of different mathematical models, comparing the fitting effects of different models, selecting the hyperbolic model to predict the final settlement after the completion of Chengde Airport, and concluding that the new high-slope measuring points of Chengde Airport The final settlement is 58.24mm. The prediction of the final settlement will be of guiding significance to the follow-up monitoring and construction of the airport and will play an important role in optimizing the construction and safety forecast of the airport follow-up projects.
