| Abstract: | It points out the construction of the No.37 pier foundtion of Beiying No.1 Douhe super large Bridge has great difficulty because of its great depth,small operating surface and instable slope.The dug pile top beam structure was adopted in the foundation construction to protect Yin-Lian railway and Jin-Shan railway from adverse impact.Through the application of digged-hole pile structural protecting system on the maintenance of foundation side slope,the desirable effect has been achieved.Combining with project practice,the design and checking of the dug pile top beam structure were introduced in detail in this paper. |
