摘要
福建某边坡进行改建,提出直接加高挡土墙进而填土拓宽,同时对新填土铺设土工格栅进行边坡加固的综合方案,基于此,采用ABAQUS对整个工程进行有限元分析。结果表明,改建后边坡的水平位移、竖直位移及安全系数分别为3.8cm、4.5cm及1.17,新建边坡安全系数偏低;对新填土铺设土工格栅后,水平位移、竖直位移分别减少36.8%(达2.4cm)和40.6%(达3.2cm),新建边坡安全系数增大63%(达1.63)。整个分析结果显示,所提方案能够满足边坡变形性及稳定性要求,且经济效益良好。
Reconstruct a slope in Fujian Province,and put forward a comprehensive scheme of directly heightening the retaining wall and then widening the fill,and laying Geogrid on the new fill for slope reinforcement. Based on this,this paper uses ABAQUS to carry out finite element analysis of the whole project. The results show that the horizontal displacement,vertical displacement and safety factor of the reconstructed slope are 3. 8 cm,4. 5 cm and 1. 17 respectively,and the safety factor of the new slope is relatively low;the horizontal displacement and vertical displacement are reduced by 36. 8% (up to 2. 4 cm) and 40. 6% (up to 3. 2 cm) respectively,and the safety factor of the new slope increases by 63% (up to 1. 63). The analysis results show that the proposed scheme can meet the requirements of slope deformation and stability,and has good economic benefits.
