測量土釘與樁的長度與質量的方法
The present invention provides a measurement of the length of the pile of soil nailing and quality, the method comprising the steps of: sensing a plurality of optical fiber sensors; the sensing fiber embedded in the measured axial pile or soil nails, where the sensing arrangement of the optical fiber length of the pile or the same as the length of soil nail; the sensing optical fiber light source and reflected waves respectively connected to the receiving means; the reflected wave receiving means and recording data collection, data processing circuit are connected in sequence; loading device using the exposed head of the pile of soil nails or axial load is applied; obtained by the reflected wave receiving means for calculating the load sensor in the axial direction under the action of the strain (or partial length change points) a physical quantity; data processing circuit using said physical quantity to get the pile of soil nailing or strain distribution, length and quality. The present invention is widely applicable to various types of soil nails or the length of the pile quality measurement, and has high reliability, low cost, resistance to electromagnetic interference, corrosion resistance and ease of use advantages.
