Design and Effectiveness Evaluation of Landslide Prevention and Control Engineering
In order to achieve reasonable landslide disaster prevention and control,based on the analysis of exploration results,the landslide prevention and control engineering design was carried out in the article,and combined with deformation monitoring results,the prevention and control effect was evaluated through deformation prediction.The results show that the stability of the landslide is unstable to stable,and the sta-bility of the rainstorm condition is the worst.The residual sliding forces of the two profiles are 18.95 and 16.43 kN/m respectively;Based on the actual engineering situation,the landslide prevention and control project is designed as a retaining wall+drainage ditch,with the drainage ditch located at the foot of the retaining wall.Both are divided into two sections,with lengths of 42 and 52 meters respectively;Through de-formation prediction analysis,it is found that although the subsequent deformation will increase,it tends to converge.In addition,the final predicted deformation values are 16.34 and 14.16 mm,which are significantly less than the control value of 25 mm,indicating that landslide prevention and control have met the design requirements.
