摘要
高边坡在水利水电工程中起着至关重要的作用,其稳定性与安全性影响着居民的安全。文章采用有限元分析方法与极限平衡算法,计算出水电站土壤的抗剪强度,根据抗剪强度分析高边坡的稳定性。通过构建高边坡岩土层模型,得出岩土的物理力学参数,并对高边坡进行应力锚索加固处理.通过实例应用分析结果可知,此种加固技术能够有效提高高边坡稳定性安全系数,对增强高边坡的牢固性与安全性具有重要作用.
High slopes play a vital role in water conservancy and hydropower projects,and their stability and safety affect the safety of residents.Therefore,the stability analysis and reinforcement technology research of high slopes of hydropower stations are proposed.Using the finite element analysis method and the limit equilibrium algorithm,the shear strength of the soil of the hydropower station is calculated,and the stability of the high slope is analyzed according to the shear strength.By constructing a rock-soil layer model of a high slope,the physical and mechanical parameters of the rock and soil are obtained,and the high slope is reinforced with a stress anchor cable.It can be known from the results of application analysis that this kind of reinforcement technology can effectively improve the safety factor of high slope stability and play an important role in enhancing the firmness and safety of high slopes.
