Abstract: The design of foundation pit support and slope in the two phase of a residential area were introduced. The surrounding terrain, elevation changes 5.8~12.35m, and surrounding built buildings close, requirements vary control on the displacement of soil excavation, combined with the surrounding circumstances were different uses natural grading, bored different support form row pile support, soil nailing wall, composite bolt retaining wall, so as to ensure the safety of the construction pit and the surrounding buildings, Combined with information construction and achieve more satisfactory results.

Keywords: foundation pit; slope; natural grading; drilling; bored different support form
