摘　　要：复合地基由岩体(土体)和增强体(桩体)两种不同材料复合而成,其基本力学性能包括微观力学性能和宏观力学性能。目前复合地基的研究主要集中在将基体和增强体分开进行研究与宏观力学性能研究等方面。从细观力学角度出发,将基体和增强统一作为横观各向同性体,研究复合地基的局部力学性能,得到了复合地基弹性应力应变场解和相应的弹性参数。A composite foundation is composed of basic body (soil) and reinforced body(piles),of which basic mechanical properties include micro and macro mechanical properties.At present,study on composite foundation mainly focuses on basic body and reinforced body separately and macromechanaical properties.This article studies the micromechanical properties of composite foundation on transverse isotropic body of taking basic and reinforced body as a whole from micromechanics;and the stress-strain elastic field solution and corresponding elastic parameters are obtained.
