水平荷载下基础与地基土相互作用数值模拟

Horizontal Loads under the Base and Foundation Soil Interaction Numerical Simulation

通过对水平均布荷载下条形基础及地基土相互作用机理分析、数学建模和数值求解.利用MATLAB PDEtoolbox工具包建立模型,网格剖分,数值求解,输出相应的点(p)、边(e)、三角形(t)数据向量,最后求出按节点编号排练的解的数值.反映了水平均布荷载下条形基础及地基土的相互作用规律,在水平荷载下条形基础和地基土在基础的底边与地基土的相互作用应力最为集中,水平和竖直方向的位移也最大.随着水平荷载的增大,条形基础的水平和竖向的位移变化越明显,随水平荷载减小,其水平和竖向的位移变化越小.

The levels are distributed load under strip footing and foundation soil interaction mechanism a- nalysis, mathematical modeling and numerical solving. Using the MATLAB PDEtoolbox Kit model, mesh genera- tion, numerical solution, the output of the corresponding point （p）, edge （e）, triangle （t） data vector, and fi- nally calculates the value of the solution node number rehearsal. Reflects the average water distributed load under strip footing and foundation soil interaction law, the highest concentration of strip foundation and the soil under the horizontal loads based on the bottom edge of the foundation soil interaction stress, displacement of the hori- zontal and vertical directions also the largest. With the horizontal load increases, the level of the strip foundation and vertical displacement of the more obvious with the horizontal load decreases, the smaller the horizontal and vertical displacement.
