基于Midas-GTS/NX的不同工况下 某边坡稳定性分析及加固措施

Stability analysis of a slope with reinforcement based on Midas-GTS/NX under different working conditions

采用Midas-GTS/NX软件中的有限元强度折减法、非线性时程等计算方法,分别对云南某边坡自然状态、降雨工况、地震工况下的稳定性进行了分析,得出边坡在连续降雨和地震工况下的安全系数分别为1.072、0.950,稳定性欠佳,需要采取加固措施。对潜在滑动面采取预应力锚杆加固,并对加固后的边坡稳定性进行了分析,结果表明,边坡达到了稳定状态,满足永久性边坡的要求。

Using the calculation methods such as finite elements strength reduction method and nonlinear time his-tory involved in Midas-GTS/NX software,the stability of a slope in Yunnan Province under natural,raining and earthquake conditions was analyzed respectively.It is concluded that the reinforcement was required to be performed for the slope of poor stability as the safety factor of the slope under continuous rainfall and earthquake condition was 1.072 and 0.950 respectively.In this paper the pre-stressed anchor was designed to reinforce the potential sliding slope and the stability of the reinforced slope was analyzed.The results show that the slope with such reinforcement is stable and comply with the requirements of the permanent slope.
