山区高等级公路多布线于河谷平缓地段,公路路基濒临水库受水库多重作用,路基沉陷、失稳等病害多发,影响道路使用性能及行车安全。文章通过分析既有库岸坍岸预测方法的适用性,研究提出适用于山区河谷型库岸坍岸的预测方法 -平衡图解法,并以云南山区冷清公路为例,利用图解法预测公路近马堵山水电站段的路基坍岸情况,对路基边坡的加固及处置方案作出评估及指导。本次研究成果能够预测圈定坍岸影响范围,在此基础上,提出工程治理方案供工程治理与预防参考。
Multi-wiring of high-grade mountainous areas in the valley smooth section, the roadbed on the verge of the reservoir by the reservoir multiple roles, roadbed subsidence, instability and other diseases occur frequently, affecting the road performance and traffic safety. By analyzing the applicability of the existing bank collapse prediction method, this paper studies and puts forward the forecasting method, which is applicable to the collapse of the river bank in mountainous area, and gives a balanced solution method. Taking the Qingqing highway in the mountainous area of Yunnan as an example, Block Shanshui hydropower station subgrade collapse bank situation, the reinforcement and disposal of subgrade slope to make assessment and guidance programs. The results of this study can predict the scope of the delineation of bank collapse, and on this basis, propose engineering governance programs for project management and prevention reference.
