Simple measurement method for high-speed railway roadbed deformation
The invention discloses a simple measurement method for high-speed railway roadbed deformation. The simple measurement method comprises the following steps that a roadbed deformation monitoring pointis drilled; a bottom flange plate, a measuring rod and a measuring rod sleeve are installed in the hole; the drilled hole is backfilled to a certain depth below a hole opening; a top flange plate anda sleeve are installed; the hole opening is backfilled; the top flange plate is fixed; a dial indicator is inserted into a number measuring sleeve for number measuring; and data are sorted and analyzed to form a monitoring report. The bottom flange plate is fixed in a roadbed stable layer, so that a measurement reference point is formed, the measurement reference point extends towards a hole opening through the multi-section measuring rod, and the measuring rod sleeve sleeves the side rod, so that the measuring rod moves along the measuring rod sleeve when rock and soil are vertically deformedfor the measuring rod reference. The top flange plate and the top sleeve are arranged at the hole end to realize the measurement reference of the roadbed surface and the installation of the dial indicator, and the roadbed deformation is obtained through the deformation of the top end of the side rod and the top end of the top sleeve.
本发明公开了一种高速铁路路基变形的简易测量方法，包括以下步骤：路基变形监测点钻孔、底部法兰盘、测杆、测杆套管安装入孔、钻孔回填至孔口以下一定深度、顶部法兰盘及套管安装、孔口回填及顶部法兰盘固定、千分表插入测数套管测数、整理和分析数据形成监测报告。本发明中将底部法兰盘固定在路基稳定层中，从而形成一个测量的基准点，同时通过多节的测杆将测量基准向孔口方向延伸，通过在侧杆外套测杆套管，保证测杆基准在岩土发生竖向变形时，测杆沿着测杆管套移动，通过在孔端设置的顶部法兰盘和顶部套管实现了路基表面的测量基准以及千分表的安装，通过侧杆顶端、顶部套管顶端的变形量得到路基变形量。
