Abstract：
Brazzaville Business Center is situated at the beach of west curve of Congo River, the surface material at the site consist of soft soil and rocks distributing alternately, and the vertical soil profile consist of scattered fine-grained soils and cemented rock body distributing alternately and nonuniformly, while the capability of site equipment is limited. In consideration of the ample manpower in local, insufficient materials and equipment, as well as hydrology and rainfall condition, the method of soil nailing wall with tube well de-watering, the utilization of manpower instead of equipment for excavation system and ground water control will be implemented to achieve the goal of this project.
