Control of Geotechnical Engineering Investigation Process for a Highway Bridge in Harbin and the Effect

Based on the natural geographical conditions of Songpu highway bridge in Harbin and the parameters required by architectural design, the key links of the geotechnical engineering investigation are determined. The paper elaborates the control of key investigation processes including platform building, drill and coring technologies, mud protection and samples storage. Based on the investigation results, the calculation was made on the bearing capacity of pile foundation and ground subsidence, and the recommended pile type was presented.
