［摘要］以某礦場的山體邊坡支護為背景，對支護后的邊坡進行了現(xiàn)場檢測，沒有出現(xiàn)破壞跡象。卸載后，殘余變形微小，P-s曲線沒有出現(xiàn)拐點。結果表明,變形及抗拔力滿足設計要求。同時進行了數值模擬，發(fā)現(xiàn)在支護后邊坡的位移比支護前變小，坡體的應力值增大，支護有效的控制了坡體的變形。各桿件的軸力在支護過程中變化也趨于合理，與設計計算基本吻合，與現(xiàn)場測試的變形曲線基本一致。說明錨桿在邊坡支護工程中有很廣泛的應用前景。
［關鍵詞］邊坡支護； 錨桿； 數值模擬； 載荷試驗

Abstract: This paper studied the mechanism of anchor on the basis of a slope in a Mine. In-site tests had been taken after the slope support finished. No damage had been found. Residual deformation was very small after unload and no inflection point had been found in the P-s curve. The results show that the deformation and pulling capacity meet the design requirements. The numerical simulation was carried out. The simulation results show that the displacement of the slope is smaller and the stress is lager than before supporting. The slope deformation is well controlled after supported. The axial force change is reasonable in the supporting process. The simulation results meet the design calculation and in-site test curves. The anchor support has a very broad application prospects in slope supporting engineering.
Keywords： slope support; anchor; numerical simulation; load test
