Abstract:
This paper introduces a kind of cross structure to neighboring foundation pits to act as the bracing system of the foundation pits. The cross beams and the cross anchors keep the retaining structure and the soil mass into an integral part. The cross structure makes full use of the stability of the rock mass and ensures the safety of the foundation pits. Based on the analysis on the engineering cases, this paper provides the structure calculation model, the key points of the calculation and the structural composition, and confirms the calculation method and the design concept. The engineering practice proves that the cross structure has unique advantages to cope with the problems of neighboring foundation pits in small site areas and complex environment.
Key words: cross structure, deep foundation pit, cross beam, cross anchor
