以广西河池机场道槽区高填方路堤工后沉降原位监测结果为基础,分析了两种指数模型、双曲线模型、幂函数模型、平方根模型和对数模型等回归参数模型在河池机场道槽区高填方路堤工后沉降预测中的适用性。通过与实测数据对比分析,确定了能较真实反映河池机场道槽区高填方路堤工后沉降规律的指数模型。采用该模型进行了道槽区路堤工后沉降预测,预测结果表明,由于道槽区高填方路堤填筑体厚度极不均匀,工后沉降变化显著,但单位路堤填高沉降量较为均匀。
Based on the post-construction settlement monitoring results of high-fill embankment in Hechi District, Hechi, Guangxi, this paper analyzes the effects of two exponential model, hyperbolic model, power function model, square root model and logarithm model on Hechi Airport Road Applicability in prediction of post - construction settlement of high fill embankment in. By comparing with the measured data, an index model that can more accurately reflect the post-construction settlement of high-fill embankment in the trough area of Hechi Airport has been determined. The model is used to predict the post-construction settlement of embankment in the channel area. The prediction results show that due to the extremely uneven thickness of embankment in the high-fill embankment in the channel area and the obvious settlement after the post-construction settlement, the settlement of embankment per unit area is relatively uniform.
