Abstract： Taking the engineering investigation of a technology research and development building in Pudong New Area as an example， based on the special geological conditions of the proposed building site and the structure of the building， the geotechnical engineering investigation methods and results of the complex geological conditions of the proposed site are analyzed. The problems encountered in the construction of pile foundation in construction investigation and the optimal treatment methods are introduced. The construction investigation and pile foundation design optimization method of this project have valuable reference significance for similar projects in this area.

Keywords： geotechnical engineering investigation; ancient river course; construction investigation; PHC pile; bearing capacity of pile foundation
