Determination of compaction parameters of clay - core dam of ni ' erji reservoir 尼爾基水利樞紐工程心墻壩粘性土料壓實(shí)參數(shù)的確定
High asphaltic concrete core dam is one of the new developing directions in dam construction of the world . it is important to study the parameters back analysis 高瀝青混凝土心墻壩是當(dāng)今世界壩工領(lǐng)域新的發(fā)展方向之一,對(duì)瀝青混凝土心墻材料進(jìn)行參數(shù)反演分析具有重要的理論意義和實(shí)用價(jià)值。
3 ) the six parameters of the asphaltic concrete core dam is inversed by least square , bayes random and bp neural network method . the sensitivity analysis of the parameters is studied 分別用最小二乘法、 bayes隨機(jī)法和bp人工神經(jīng)網(wǎng)絡(luò)法反演瀝青混凝土心墻材料的六個(gè)參數(shù),并對(duì)參數(shù)的敏感性進(jìn)行研究。
Combined with the behavior in 1st constructing period of maopingxi dam , nonlinear fem calculation and material parameter back analysis are applied to the maopingxi asphaltic concrete core dam 本文結(jié)合茅坪壩期施工情況,對(duì)茅坪溪瀝青混凝土心墻壩進(jìn)行了非線性有限元應(yīng)力應(yīng)變計(jì)算和壩體材料參數(shù)反演分析。
At mean time , it is very important to study and adopt new dam construction techniques in the world , such as to focus on the wide application of the rock - fill concrete deck and rolled asphalt concrete core dams 同時(shí),學(xué)習(xí)和引進(jìn)國(guó)外壩工新技術(shù),如重點(diǎn)推廣應(yīng)用的混凝土面板堆石壩和碾壓式瀝青混凝土心墻壩等新壩型。
