Thirty roots of precast reinforced concrete piles and bored and cast - in - place piles in xi ' an had been trained with this model , and nine roots o f precast reinforced concrete piles and eight roots of cast - in - place piles had been predicted by simulating . when contrasted and analyzed the predicting result and actual numerical value , the error is always less than 20 % ( mostly within 15 % ) , which has achieved a better result
利用该模型对西安地区钢筋混凝土预制桩、钻孔灌注桩各30根作为样本进行了训练，并分别对9根钢筋混凝土预制桩和8根钻孔灌注桩进行了仿真预测，将预测结果与实测值进行了对比分析，其误差都在20以内(大部分在15以内) ，取得了较好的结果。
