基于高填路堤现场实时沉降观测数据,采用双曲线法、指数曲线法、Asaoka法等分别对武汉天河机场第二通道高速公路S6标K12+300断面路堤沉降变形进行拟合分析和预测,并对拟合预测结果进行方差检验和关联度分析,以揭示高填路堤沉降变化规律,探讨实测沉降和曲线拟合与预测之间的关联。结果表明,指数曲线法预测结果精度高,效果最好;对于现场实时观测数据的处理分析,应以填筑后期的沉降观测值为主,尽量减少选用填筑初期的观测信息,建议采用150d实测数据进行沉降预测及变形控制。
Based on the real-time settlement observation data of high embankment embankment, the settlement and deformation of embankment on S6 K12 + 300 cross-section of the second expressway of Wuhan Tianhe Airport were fitted and analyzed by hyperbolic method, exponential curve method and Asaoka method respectively. Variance test and correlation analysis of the fitting prediction results are carried out to reveal the variation law of settlement of high embankment and to explore the relationship between the measured settlement and curve fitting and prediction. The results show that the exponential curve method has the best accuracy and the best result. For the analysis of the real-time observation data, the observation of the post-filling settlement should be the main method to minimize the observation information during the initial filling period. Data for settlement prediction and deformation control.
