摘要: 為了研究加筋土擋土墻的破壞機理和加固技術,以某立交橋擋土墻加固工程為例,首先分析了加筋土擋土墻的失穩原因,采用了噴射混凝土、預應力錨桿、注漿聯合加固方案,然后對施工中的主要技術難題進行研究并提出了解決方案,最后用國際流行的軟件FLAD^2D進行數值模擬.加筋土擋土墻加固后預應力穩定,墻面無變形,表明聯合加固方案是可行的.

Abstract: In order to study the failure mechanism and reinforcement technique of reinforced earth retaining walls, the reinforcement project of a crossroad was taken as an example. The failure mechanism was analyzed firstly. A united measure of shotcrete lining on the surface, pre-stressed anchor and injection was applied. Main problems in construction were discussed and solved. Lastly, the reinforcement effect was simulated with FLAC^2D. After the reinforcement, stable stress and little deformation indicate the united measure is effective.
