Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] see Figure 1-4 , a method for converting the horizontal displacement of a cross-section embankment to monitor the deformation. The specific implementation steps are as follows:

[0042] Step 1: Layout of cross-section monitoring points and acquisition of monitoring point coordinates. The monitoring sections are laid out in the direction perpendicular to the embankment axis, and four monitoring points are arranged in each section, and the coordinates (N i ,E i), i=1, 2, ..., n, where i is the number of the measuring point.

[0043] Step 2: Use the least square method to fit the monitoring section direction line y=ax+b perpendicular to the dike axis, where x is the E (east) direction coordinate value of the monitoring point, y is the N (north) direction coordinate value, and stipulate The straight line direction is from the backwate...

Abstract

The invention provides a converting method of horizontal displacement monitoring deformation amount of a sectional dike, and belongs to the field of water conservancy project management and deformation monitoring. The converting method is mainly used for solving the problem of how to convert the monitoring deformation amount to the amount of deformation perpendicular / parallel to the axis directionof the dike after multi-period coordinates of monitoring points are measured. Aiming at solving the problem, the converting method of the horizontal displacement monitoring deformation amount of thesectional dike is designed according to the relationship among the deformation direction, the section direction and the axis direction of the dike, thus the monitoring deformation amount can be accurately converted to the amount of deformation perpendicular / parallel to the axis direction of the dike, and the deformation direction is indicated. Meanwhile, the converting method is suitable for deformation monitoring work of horizontal displacement of the sectional dike, and can be applied to a GPS deformation monitoring system, a measurement robot monitoring system and the like.

Description

technical field [0001] The invention belongs to the field of water conservancy project management and deformation monitoring, and relates to a method for converting the deformation amount of the horizontal displacement monitoring of a cross-section embankment. Background technique [0002] The safety of embankment projects is the key to ensuring river flood control and disaster reduction. If there are hidden safety hazards in embankment projects, or if the operation and management personnel do not understand the safety status of embankments, the operation risks of embankments will be very high, and their normal benefits will not be exerted. Therefore, it is very important to strengthen the deformation monitoring of embankment engineering. [0003] Dikes will produce different deformations under loads such as self-weight, water pressure, uplift pressure, ice pressure, sediment deposition pressure and temperature. Deformation monitoring is the most direct monitoring of dikes,...
