Abstract: Basing on construction monitoring of the supporting system for a deep foundation pit, a study on the displacement, settlement, inner force and water level are carried out. It is indicated that the horizontal displacements of timbering stakes as well as observation spots outside increase step by step along with the increase of the excavation depth and construction time. Meanwhile its increasing velocity tends to steady gradually. In addition, the displacements are also related to the location of building nearby and the supporting condition. The settlement of building nearby increases with time, and is greater near to the pit. The settlement of standing column and the apophysis of earth are related to the bearing weight and the form of pits. The axial force of support is related to earth condition, support rigidity as well as order and velocity of construction, etc.The partiality value of stake body is small; the bottom can be calculated according to axial forces. The early-warning value is taken into account in this paper.

Key words: supporting system for foundation pit, displacement, settlement, construction monitoring, early-warning value
