斜坡桥梁桩的基础加固优化技术研究
|
摘要
地形、地质条件的复杂性是公路建设中需要面对的难题之一,在山区公路建设中,斜坡桥梁桩的基础加固是确保公路工程质量的关键。通过采用锚杆(索)加固斜坡桥梁桩的基础,控制公路水平位移和公路沉降量等,从而对降低实际施工的工程投资和对实际工程优化做出合理的规划提供有效的帮助。
The complexity of the terrain and geological conditions is one of the problems that have to face in the road construction in mountain areas.In the construction,the slope bridge pile foundation reinforcement is the key to ensure the quality of highway projects.Bolt or cable is adopted to reinforce the basis of slope bridge pile,and control horizontal displacement and road subsidence,etc.This paper can provide effective help to reduce the actual construction of the project investment and optimize the project and to make a reasonable planning.
