Abstract：
Heavy miscellaneous fill layer exist on the north and east of a foundation pit locality. According to engineering layout, manual dig-pouring pile-prestressed anchors system were used in the north of the pit, channel steel frame girder with prestressed anchor cables were used in the east of the pit. By monitoring data obtained during the pit excavation construction, the two deep pit supporting methods are both control supporting structures deformation effectively on mixed fill area, insure the safety of foundation pit and underground structure construction, which offers reference for similar works.
