Research on Calculation Theory of Double-Row Piles Retaining Structure

Abstract:

The double-row piles retaining structure (DRPRS) is widely applied in the excavation engineering, but its calculation theory is immature and in appropriate. Based on the theory of earth pressure distribution, the distribution characteristics of earth pressure is analyzed to different layout form, and the general formula of earth pressure is derived. From the perspectives of the morphology of slip surface, linear slip surface morphology and broken-line slip surface morphology are proposed based on the feature of the DRPRS. A new calculation model is proposed combining the earth pressure and slip surface morphology. On this basis, one example is used to analyze the force and deformation mechanism of the DRPRS in detail. The research results can guide the engineering practices and promote the development of calculation theory for the DRPRS.
