Abstract:

One of the efficient analysis methods for slope safety monitoring results is to achieve 3-d visualization of spatially monitored physical quantity in monitoring data field. Through introducing the MatrixVB component into Visual Basic, the spatial data of monitored data field was interpolated by programming Visual Basic program with calling Matlab interpolation functions, the 3-d visualization of monitoring physical quantity in the slope engineering is realized on the Visual Basic platform by using parametric modeling method and X3D visual technology. This method combines the advantages of both Matlab interpolation functions and Visual Basic and can solve the interpolation problem of monitoring points in monitored slope area effectively. Taking one slope of a hydropower station for example, the 3-d nephogram of slope monitoring data field in the slope engineering is realized, which can provide theoretical basis for processing the safety monitoring results of slope engineering.
