Embodiment

[0041] 1. Project overview

[0042] The deep excavation of a railway embankment forms a 47-meter-high slope. The slope is divided into three levels and reinforced with prestressed anchors. The slope ratio of the first level is 1:0.25, and the slope ratio of the second and third levels is 1: 0.5, and the slope heights of each level are 15.0, 16.0, and 16.0m respectively; a 2.0m wide platform is set between each two levels. The anchor rods are arranged in a rectangle, the vertical and horizontal distances are 4.0m, the drilling diameter is 130mm, each anchor rod adopts 5 pieces of φ15.24 steel strands, the locking tonnage is 777kN, and the anchorage adopts OVM15--5 type. The borehole and the horizontal plane are 15°, the strength level of the steel strand is 1860MPa, the bonding strength between the cement mortar and the borehole wall is 0.5MPa, the bonding strength between the steel strand and the cement mortar is 1.4MPa, and the anchor is pull-out resistant The safety factor ...

Abstract

The invention discloses a slope back analysis method based on anchoring load monitoring data, which starts with the anchoring load monitoring data to establish the relations among monitoring data and equivalent mechanical parameters of a rock-soil body as well as the variation trend of slop stability coefficients according to an objective functional expression. The slope back analysis has the technical effect that the mapping relation between the equivalent mechanical parameters of the rock-soil body and the anchoring load monitoring data is established through an objective function to calculate the equivalent mechanical parameters of the rock-soil body where an anchoring body is positioned, and further deduce the variation trend of the slope stability coefficients.

Description

technical field [0001] The invention relates to a load data processing technology in slope treatment engineering, in particular to a slope back analysis method based on anchor load monitoring data. Background technique [0002] At present, prestressed anchors or anchor cables are widely used in slope treatment engineering. In order to ensure the reliability of the structure, it is necessary to strengthen the prestressed anchors or anchors during the construction of the slope and within a period of time after the construction. The anchor load of the anchor cable is monitored, and a large amount of monitoring data obtained is analyzed to know whether the prestressed anchor rod or anchor cable fails. The load data obtained from the monitoring can not only reflect the reliability of the structure itself, but also reflect the relevant mechanical information of the rock and soil mass. However, how to maximize the value of the monitoring data is rarely studied in depth. Research. ...
