Abstract The main body of Dongying Yellow River Bridge is a continuous rigid-frame bridge of a prestressed reinforced concrete structure, with a span of 116+200+220+200+116 meters. The tenth pier of the main bridge takes its root into the riverbed. Its foundation is mainly made up of 49 non-displacement piles, which are 1.5 meters in diameter and 115 meters in length, and the center distances between the piles are 3.9 meters only. This paper presents the boring control technology for in-water construction of the non-displacement piles for the tenth pier of the bridge mentioned above under complex geological conditions on the bed of Yellow River.
