| Abstract: | The construction of the No. 14 pier foundation of Hongning River super large bridge has great difficulty because of its great depth and instable slope. The dug pile wall structure was adopted in the foundation construction to protect the 222th provincial read and underground fiber optic cable from adverse impact. The design and calculation of the dug pile wall structure were introduced in detail in this paper; it can be referred to by similar engineering. |
