双排桩桩间土体加固对桩土变形影响研究

Research on the Deformation of the Pile and Soil of Double-row Piles with Reinforced Soil

双排桩支护结构中,桩间土体加固是一个需要考虑的重要因素。为此,本文采用有限元程序MIDAS/GTS建立双排桩支护结构的有限元模型,验证了桩间加固对桩土位移的减小作用,分析了桩间土体不同加固深度对桩土变形的影响,其研究结果为双排桩的桩间土加固深度设计提供了依据。

Soil reinforcement between the piles is an important factor to consider in double-row piles retaining structure. Therefore, in this paper, the double row pile supporting structure finite element model is established by using the finite element program MIDAS/GTS, the effect on the reduction of the pile and soil displacement of double row-piles with reinforced soil is verified, and the influence of different depth of reinforced soil between piles on the pile and soil deformation is analyzed. The results provide the basis for the reinforcement depth designation of the double row piles.
