【摘要】 分析了水泥土围护墙弹性模量对于控制基坑变形的重要性、根据上海某钢管水泥土墙基坑支护的工程实例建立ABAQUS平面二维有限元模型,计算钢管水泥土围护墙等效弹性模量,量化了内插钢管对提高水泥土重力式围护结构的支护强度所起到的作用,并对钢管长度、外径、间距和插入位置进行了参数分析。更多还原

【Abstract】 The importance of the elastic modulus of cemented soil retaining wall to controlling deformation of foundation pits is analyzed.A 2D ABAQUS plane finite element model is set up on the basis of a excavation project in Shanghai.The equivalent elastic modulus of the wall embedded with steel pipes are calculated.The result quantifies the effect of steel pipes in raising strength of the retaining wall.Some parameters of the steel pipes such as length,external diameter,insert position and distance between two pipes,are also analyzed.更多还原
