Research on Stability and Strengthening Measures of Highway Red Clay High Slope under Heavy Rainfall
In order to study the stability of highway red clay high slope under heavy rainfall and establish safe and effective reinforcement and protection measures,this paper relies on a grade 7 slope project of Jikang high-speed reconstruction and expansion project,and uses numerical simulation method to quantify the influence of rainfall intensity and duration on the stability of red clay high slope.The results show that the natural stability of the high slope is poor during the construction process,and continuous rainfall is easy to cause the slope instability during the construction period.When the continuous rainfall is 480 mm/d for 48 hours,the safety factor of the slope is reduced by 20.7%,and the reinforcement of lattice anchor can better constrain the displacement of the slope and ensure the safety and stability of the red clay high slope under the condition of heavy rain.
