摘要: 根據山東省淄博市梧臺立交橋加筋土擋土墻加固的工程實際,結合理論計算,討論了高壓注漿提高錨固力的原理,提出了局部采用雙層鋼筋網的噴漿支護方法.結果表明,該加固方法有效地限制了墻體的側向位移,加固效果良好,適用于失穩擋土墻加固.Abstract: Aimed to the reinforcement of reinforced soil retaining walls at Wutai cloverleaf junction of Zibo, Shandong province of China and based on the correlative theoretical calculation, a method of enhancing the anchoring force by high-pressure grouting was discussed. The method of grouting with two local layers of steel bar nets was proposed. The result indicated that the lateral displacement was limited effectively with a satisfactory reinforcement effect.
