Abstract Research purposes: The Tianjin traffic transfer junction center station is a large and deep pit with complicated engineering structure, geological condition and environmental condition. Adopting appropriate investigation methods, supplying reasonable design parameters and providing scientific geotechnical engineering evaluation and suggestions are important parts of the conjunction construction.
Research results: By complex exploration methods, which including geological drilling, in-situ measurement and soil tests in or out doors, the engineering geological condition and hydro-geological condition is found out and the parameters of the site soil and water are provided. The engineering problems such as stability and feasibility of the site, the style of pit-supporting structure , expanding and piping of pit bottom , anti-floating of the structure, controlling measures of dewatering and so on are analyzed and estimated, and pertinent engineering suggestions are provided as well, which offers scientific basis for the engineering design and construction.
