| 摘 要： | 运用Geoslope对某高速公路边坡进行稳定性分析，评价边坡在开挖垮塌后的稳定性。根据稳定性计算结果提出抗滑桩治理措施，并采用FLAC3D数值模拟方法对治理效果进行了评价。由于典型断面桩顶位移量超过规范要求，进一步进行桩前土体注浆措施，处治效果良好，桩顶位移量满足规范要求。结果表明，治理后边坡稳定性显著增强，治理效果显著。

Slope Stability Analysis and Support Design Based on Geoslope and FLAC3D |
| |
| Abstract: | The stability of the slope of an expressway was analyzed by using Geoslope to evaluate its stability after excavation and collapse. According to the stability calculation results, the governance measures for anti-slide pile were proposed and the governance effect was evaluated by using FLAC3D numerical simulation method. Because the displacement of the pile top with typical section exceeded the requirements of the code, further grouting measures of soil mass before the piling were carried out, with good treatment effect and the displacement of the pile top met the requirements of the code. The results show that the slope stability is enhanced and the treatment effect is remarkable after governance. |
