Application of double-row piles retaining structure in electric power engineering

Abstract

Advantage and analysis models of double-row piles retaining structure are described in this paper. Based on project practice of double-row piles retaining structure in Huaneng Fuzhou power plant, multi-schemes of supporting and retaining structure have been contrasted and the optimal scheme is recommended. To deal with the soil loss between piles, scheme of small interval and small diameter pipes shall be employed and jet grouting shall be used to improve the soil between piles, so that the soil shall be self-stable on the front surface. The success of the project ensures the operation of the existing power plant and construction of the building plant, which is one avail application case for reference of similar project.
