摘　　要：采用有限元数值计算方法,针对路堤荷载作用下水泥土搅拌桩复合地基的地表沉降、下卧层沉降、桩体上部、下部的刺入变形、地基土侧向变形等进行系统研究,探讨桩体和土工格栅的应力变化规律,可为类似工程的设计、施工提供参考。Finite element numerical calculation is used to systematically study ground surface settlement, subjacent bed settlement, penetrating deformation for the upper and lower parts of pile, and lateral deformation of foundation soil etc, discuss the stresses variation laws of pile and geo-grid. The research results will serve as a guide in the design and construction of similar projects.
