摘　　要：高原机场地处特殊的地理环境,机场跑道易产生不均匀沉降。对此,根据地基沉降的特点,引入LSTM模型,同时引用鲸鱼算法WOA对LSTM模型进行参数优化,构建WOA-LSTM组合预测模型。论文以西南山区某高原机场为例,选取跑道瞄准点两侧A、B、C、D四个断面为监测点,以测试样本的均方根误差最小为适应度函数,其预测结果与LSTM模型预测结果进行对比分析。结果表明,论文所构建的LSTM模型和WOA-LSTM模型在高原机场地基沉降预测中与实测值基本吻合,但优化后的LSTM模型预测值更加接近现场监测值,预测值与监测值的相对误差小于3%,该地基沉降预测模型可为高原机场的设计、建设、运营管理和后期维护提供可靠的理论参考。Because of the special location of the plateau airport,the differential settlement of runway is easy to occur.In this regard,according to the characteristics of foundation settlement,the LSTM model is introduced,and at the same time,the LSTM model parameters are optimized by using the whale algorithm WOA,and a combined WOA-LSTM forecast model is constructed.Taking a plateau airport in Southwestern Mountain Area as an example,this paper chooses four segments A、B、C and D on each side of the target point of the runway,and compares their forecast results with those of LSTM model,which takes the minimum root mean square error as fitness function.The results show that the LSTM model and WOA-LSTM model constructed in this paper basically match the measured values in the prediction of foundation settlement in plateau airports,but the predicted values of the modified LSTM model are closer to the on-site monitoring values,and the relative error between the predicted values and the monitoring values is less than 3%,and the model can be used to provide a reliable theoretical basis for the design,construction,operation and maintenance of the plateau airfield.The model can provide a reliable theoretical reference for the design,construction,operation and maintenance of highland airports.
