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 利用該模型對(duì)西安地區(qū)鋼筋混凝土預(yù)制樁、鉆孔灌注樁各30根作為樣本進(jìn)行了訓(xùn)練,并分別對(duì)9根鋼筋混凝土預(yù)制樁和8根鉆孔灌注樁進(jìn)行了仿真預(yù)測(cè),將預(yù)測(cè)結(jié)果與實(shí)測(cè)值進(jìn)行了對(duì)比分析,其誤差都在20以內(nèi)(大部分在15以內(nèi)) ,取得了較好的結(jié)果。
