摘要
文章基于Slide选用Bishop法、M-P法和Spencer法,对昆明绕城公路K100+560边坡的稳定性进行分析,在天然工况、无堆载下昆明绕城公路K100+560边坡3种模拟方法的安全系数平均值为1.483,在天然工况、有堆载情况下安全系数平均值为1.081,在暴雨工况、无堆载情况下安全系数平均值为1.024,在暴雨工况、有堆载情况下安全系数平均值为0.803。天然工况下安全系数比暴雨工况下高,坡体表面无堆载情况下安全系数比有堆载情况下高。采取锚固技术和微型桩加固措施后,在暴雨工况、有堆载工况叠加时,昆明绕城公路K100+560边坡的安全系数平均值可以达到1.307,符合工程稳定性要求。
Based on Slide,Bishop method,MP method and Spencer method are used to analyze the stability of k100+560 slope of Kunming Ring Road.The average safety factor of three simulation methods for k100+560 slope of Kunming Ring Road under natural working conditions without loading is 1.483.The average safety factor is 1081 under natural conditions with loading.The average safety factor is 1.024 under heavy rain conditions without loading.The average safety factor is 0.803 under heavy rain with loading.The safety factor under natural conditions is higher than that under heavy rain conditions,and the safety factor is higher without loading than that with loading.After adopting anchoring technology and micro-pile reinforcement measures,the average safety factor of k100+560 slope of Kunming Ring Road can reach 1.307 under heavy rain conditions and superimposed working conditions,which meets the requirements of engineering stability.
