摘要
分析了大坝受时效、温度及水位变化影响产生非线性位移,提出了统计-支持向量机模型,实现了对土石坝的位移分析与预测。
To analysis and forecast of dam＇s nonlinear shift caused by time, temperature and water level, we proposes a new model called statistic-support vector machine, which is applied on analysis and forecast of embankment dam＇s shift. The new model can solve the problem above while the statistic model can＇t.
