桩板式挡土墙斜坡路段有效嵌固段深度的确定方法

Determination of Effective Embedded Segment Depth of Slope Section of Pile Plate Retaining Wall

斜坡路段桩板墙支挡结构嵌固段的有效性关系到工程的安全性和经济性。以实际工程为例,提出采用极限平衡的近似计算方法确定其有效嵌固深度,运用于实际工程中达到了预期效果。

Pile-plate retaining wall is widely used in the construction of highway in mountainous area. The effectiveness of the retaining structure of the pile wall of slope section is often ignored by engineering technicians,and the safety and economy of the engineering will be considered. As an example of practical engineering in the paper,the method to determine the effective embedded depth is proposed by using approximate calculation method based on ultimate balance principle,and the desired results are achieved.
