Foundation pit horizontal displacement automatic monitoring method and system based on virtual center point
The invention discloses an automatic monitoring method and system for horizontal displacement of a foundation pit based on a virtual center point, and the method comprises the steps: respectively confirming the arrangement point positions of field monitoring based on the position of a current foundation pit, and constructing the geometric features of the foundation pit, calculating the plane distance from each monitoring point to the corresponding virtual center point of the foundation pit, and reducing the calculated plane distance to the corresponding direction perpendicular to the sideline of the foundation pit; and calculating a horizontal displacement value corresponding to the horizontal displacement monitoring point according to the foundation pit sideline type to which the monitoring point belongs. According to the method, the appropriate virtual center point is set, the calculation process of the horizontal displacement value of the monitoring point and the judgment condition of the deformation direction of the monitoring point are greatly simplified, and meanwhile the horizontal displacement calculation formula of the arc sideline foundation pit is given on the premise that the algorithm complexity is not increased; the problem of calculation of the horizontal displacement value on the arc side line is well solved.
本发明公开了一种基于虚拟中心点的基坑水平位移自动化监测方法及系统，该基于虚拟中心点的基坑水平位移自动化监测方法包括：基于当前基坑的位置分别确认现场监测的布置点位，构建基坑几何特征，计算各监测点到其对应基坑虚拟中心点的平面距离，将计算得到的平面距离归算到对应的垂直基坑边线方向上；根据监测点所属的基坑边线类型计算水平位移监测点相应的水平位移值。本发明通过设立合适的虚拟中心点，大大简化了监测点水平位移值的计算过程和监测点变形方向的判定条件，同时在不增加算法复杂度的前提下给出了弧形边线基坑的水平位移计算公式，较好的解决了弧形边线上水平位移值的计算难题。
