基于加筋材料的拉拔试验结果和极限平衡理论,针对具体边坡工程进行了不同加筋方案的计算与分析,对比了计算模型和设计方法的适用性,给出了满足边坡稳定条件的最佳设计方案。计算结果表明:采用改进瑞典法或荷兰法的计算结果相近且较原瑞典法有明显的提高,更能体现加筋效果;地震效应和地下水对加筋结构有较大影响;水利法应用于稳定地基上加筋边坡目的性强,能获得满足稳定性条件的合理布筋量;当地下水位较高时,筋材宜通铺。双层加筋效果较单层加筋有明显提高,但并非后者的简单叠加。单层加筋时,铺设位置对于边坡稳定性的影响有限,若铺设于坡身更能减少布筋量,降低造价。对比分析还表明,无论采用何种加筋方式,加筋前后的最危险滑弧位置均会发生改变,后者会向边坡中心和地基深处发展,对于提高其稳定性有明显作用。 Based on the drawing test results and the limit equilibrium theory of reinforced materials, the different reinforcement schemes are calculated and analyzed according to the specific slope engineering. The applicability of the calculation model and the design method is contrasted. Best design. The calculation results show that the results obtained by using the improved Swedish or Dutch methods are similar and can be obviously enhanced compared with the original Swedish method, which can better reflect the reinforcement effect; the seismic effect and groundwater have greater influence on the reinforced structure; and the water conservancy method is applied to the stable The purpose of reinforced slope on foundation is strong, and the reasonable amount of reinforcement can be obtained to meet the stability conditions. When the local water level is high, the tendons should be opened. The effect of double-layer reinforcement is obviously improved compared with single-layer reinforcement, but it is not a simple superposition of the latter. When the single layer is reinforced, the laying position has a limited impact on the stability of the slope. If it is laid on the slope, it can reduce the amount of cloth and reduce the cost. The comparative analysis also shows that no matter what kind of reinforcement method is adopted, the position of the most dangerous slippery arc before and after reinforcement will change. The latter will develop to the center of the slope and the depth of foundation, which has a significant effect on improving its stability.
