Multi-dimensional deep deformation monitoring method for high fill side slope

Abstract

The invention discloses a multi-dimensional deep deformation monitoring method for a high fill side slope. The method comprises the following steps that an original stratum and filling body boundary are defined; two holes with the same depth are formed in the high fill side slope, one drilled hole is used for monitoring layered settlement of a filling body, the other drilled hole is used for monitoring horizontal displacement of the filling body, and sensors with the number in multiple relation are evenly distributed in the two holes in the depth direction; collecting is carried out on layered settlement and soil body fixed type inclinometry monitoring data at every time interval delta t; and integration and data transmission of two monitoring items of layered settlement and soil body fixed type inclination measurement are carried out. By means of the method, multi-dimensional deep deformation monitoring of the high fill side slope can be achieved, and two-dimensional deformation, comprising horizontal displacement and vertical displacement of each point, of the filling body along the drilled holes is obtained; and monitoring of the different monitoring items is combined, multi-dimensional deep deformation of the high fill side slope is obtained, the side slope stability can be accurately mastered, and the method is simple, convenient, high in applicability and convenient to implement.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a method for monitoring multi-dimensional deep deformation of high fill slopes. Background technique [0002] In high fill slope engineering, there are not only horizontal displacement, but also vertical displacement of soil at different depths. It is often necessary to monitor the sub-layer settlement and horizontal displacement of the soil body. The purpose is to grasp the settlement and horizontal displacement of the soil layer at different depths and in different periods in real time, so as to predict the settlement trend of the filling body and the high filling slope. stability. However, in the deformation monitoring of high fill slopes, the horizontal displacement and vertical displacement of the filling body are often monitored independently, and there is no three-dimensional monitoring system for the deep deformation of the slope, and the obtained monito...
