| 摘 要： | 预应力锚杆格子梁以其造价低廉、治理效果良好在边坡工程中得以大量应用。结合某高速公路k253＋700-k254＋220边坡工程，将预应力锚杆格子梁加固技术应用于该工程，然后选取该边坡农机天桥下方k253＋900边坡，建立有限元模型并分析了预应力锚杆格子梁加固方案的加固效果。分析结果表明，采用一级边坡锚杆预应力格子梁加固方案的加固效果非常职显。最后结合现场监测的数据分析，验证了该加固方案的有效性。

| Abstract: | The prestressed anchor lattice beam with its low cost and the fine effect was to be wide- ly aplied in the slope. This paper combined with a highway k253 ＋ 700 - k254 ＋ 220 slope engineering, the prestressed anchor lattice beam reinforcement technique is applied to the project. Then the slope of k253 ＋ 900 under the farm machinery bridge was selected, and was established the finite element model and the prestressed anchor lattice beam reinforcement＇ s reinforcement effect were analyzed. The analysis results showed that the level 1 of slope＇ s anchor prestress lattice beam reinforcement scheme of reinforce- ment effect is very obvious. At last, combined with field monitoring data analysis, the effectiveness of the proposed strengthening scheme was verified. |
