Abstract

Based on a new pedestrian bridge project on Fuchun River in Hangzhou, this paper carries out special steel pipe pile cofferdam support design for its underwater pier cap during construction, analyses and studies several problems existing in the design of steel pipe pile cofferdam, carries out calculation and analysis according to two-dimensional and three-dimensional modeling and refers to the engineering experience of similar projects, and takes the following main solutions. Firstly, soil unloading measures are taken along the river bank. In order to reduce the earth pressure load on the shore side, the construction platform of the top-supported steel convenient bridge is built to reduce the horizontal construction load on the shore, and balance the water and soil sides by two measures to meet the safety requirements of the design of the steel pipe pile cofferdam, reduce the overall deformation and displacement of the steel pipe pile cofferdam, and during the construction of the underwater cap. The monitoring data of each foundation pit of steel pipe pile cofferdam are within the normal safety range, and the construction of underwater pier caps has been completed satisfactorily, which can provide design ideas and references for similar projects.
