Abstract

The invention belongs to the technical field of geotechnical engineering monitoring, and discloses a steep slope surface horizontal displacement test method which comprises steps of setting a slope bottom monitoring point at the bottom of a slope, and monitoring the horizontal displacement of the slope bottom monitoring point by using a total station instrument to obtain the slope bottom monitoring point horizontal displacement; setting a slope surface monitoring point on a steep slope surface, and measuring the relative displacement of the slope surface monitoring point relative to the horizontal direction of the slope bottom monitoring point by using an inclinometer; processing the slope bottom monitoring point horizontal displacement and the relative displacement of the slope surface monitoring point relative to the horizontal direction of the slope bottom monitoring point by using a vector superposition method so as to obtain the horizontal displacement of the slope surface monitoring point as the steep slope surface horizontal displacement. The method provided by the invention can realize high-precision and convenient long-term monitoring of the horizontal displacement of a steep slope surface greater than 65 degrees.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering monitoring, in particular to a method for testing the horizontal displacement of a steep slope. Background technique [0002] Geological disasters of slope landslides occur frequently in our country, and once a slope landslide occurs, it often causes huge losses of personnel and property. The existing horizontal displacement test of slope surface is usually carried out by total station. In general, for high and steep slopes, the frequency of monitoring and testing is high, the number of times is high, and the testing period is long. In the prior art, when a total station instrument is used for slope testing, monitoring points need to be set on the slope surface, and each test requires monitoring personnel to climb up the slope and set up optical prisms at the corresponding monitoring points, and then Testing with a total station is very inefficient, and is often affected by the ...
