Simulation of Measuring Method for Deformation Reaction Point of Raft Foundation under Circular Structure

采用传统测量方法受到不同程度变形的影响,导致测量精准度较低。为了解决上述问题,提出了圆形结构下筏式基础变形反力点测量方法仿真。依据筏式基础变形特征,采用静力分析法确定特征系数,根据静力平衡原则求取反作用力,通过调整反作用力获取近似解,在圆形结构筏式基础示例图的支持下,测量基础变形刚性和基础变形柔性的基础变形反力点。分别分析刚性和柔性基础沉降测点,并绘制出基础中心轴沉降曲线,依据该曲线,测量刚性和柔性基础变形反力点,得出刚性基础基底反作用力大于两个端点反作用力点的结论。在筏式基础板下,设置硬件环境和软件环境参数,在仿真环境支持下,对提出的方法进行仿真分析,并分别在刚性和柔性基础变形基础下,对传统方法与所提方法进行对比分析,由对比结果可知,所提方法测量精准度较高,能为建筑领域提供技术支持。

Traditionally,the measurement methods are affected by different degrees of deformation,resulting in low measurement accuracy.Therefore,the simulation of measuring method for the deformation reaction point of raft foundation under circular structure was presented.Based on the deformation characteristic of raft foundation,the feature coefficients were determined by static analysis method,and the reaction force was calculated by the principle of static equilibrium.After that,the approximate solution was obtained by adjusting the reaction force.With the support of example of circular raft foundation,the reaction points of rigidity and flexibility of foundation deformation were measured.The settlement measurement points of rigid foundation and flexible foundation were analyzed.Meanwhile,the settlement curve of central axis of foundation was drawn.Based on the curve,the reaction points of deformation of rigid and flexible foundations were measured,so that the conclusion that the reaction force of rigid foundation was larger than that of two endpoints could be drawn.Under the raft foundation slab,the parameters of hardware and software environment were set.The proposed method was analyzed in simulation environment.The proposed method was compared with the traditional method on the basis of rigid and flexible foundation deformation.The comparison results show that the proposed method has higher measurement accuracy,which can provide technical support for the construction field.
