摘要
运用ANASYS有限元分析软件,构建地基基本的三维模型,地基支承刚度的空间改变是由地基变形模量的改变来体现的,研究地基支承刚度改变,基本的筏板厚度保持不变时,基本的沉降值线的散布规则,证明了地基变刚度对改善荷载传递体系、减少基础沉降差、筏板内力和厚度、上部结构次应力的作用。
By use of ANASYS software of finite element analysis, basic 3D model of ground foundation is built, and space change of ground foundation support rigidity is reflected by the change of foundation deformation modulus, and through the research on distribution rule of basic sedimentation value line when basic raft thickness is kept unchanged in order to study the change of foundation support rigidity, it has proved the effect of variable rigidity of foundation on improving the load transfer system, reducing the differential foundation settlement, internal force and thickness of raft, as well as secondary stress of upper structure.
