摘要
悬臂式挡土墙是一种轻型的挡土结构,具有构造简单、施工方便、质量较轻的特点,应用比较广泛。但是由于其墙高有限制,不适合处理高填土边坡。通过借鉴锚杆挡土墙的结构形式,考虑在悬臂式挡土墙上加设锚杆,利用拉锚结构抵消墙体背后部分水平推力,来处理高填土边坡。结合工程实例,通过对设计方案进行比较和验算,采用悬臂式挡土墙上加设锚杆的设计方案从理论上是安全可行的。通过施工效果检验和沉降位移监测结果,对悬臂式锚杆挡土墙处理高填土边坡的合理性和安全性做出了评价。
Cantilever retaining wall is a kind of lightweight retaining structure which is used most widely for the characteristics of the simple structure,the easy construction and the light quality.Due to its limited height,it＇s not suitable for high filling slope.Based on the structure form of anchor retaining wall,the anchors could be added to cantilever retaining wall,using the anchor structure to offset the part of the horizontal thrust,the cantilever retaining wall could be used to deal with high filling slope.Combined with the engineering example,comparing and checking the design,the anchored cantilever retaining wall is safe and feasible in theory.Through the construction inspection results,combining the settlement and displacement monitoring results,the rationality and security of anchored cantilever retaining walls in reinforcing high filling slopes are evaluated.
