高陡边坡三维实体变形预测的研究

从高陡边坡变形预测的机理出发,综合考虑三维点变形之间的相互影响以及变形的时间效应。根据三维实体变形预测理论,利用Matlab编制变形预测程序,建立了高陡边坡三维实体变形模型。结合实际工程监测资料,回归出相应的参数,并进行后续变形预测。结果表明,预测值与实际监测值相接近,相对误差在4%以内,由此为滑坡预警和安全生产提供了依据。

Study on High and Steep Slope Deformation Prediction of 3D Entity Theory

According to the basic mechanism of high and steep slope deformation prediction ,the study considers the mutual influence of three dimension points and time effect of the deformation .Based on the deformation prediction of 3D entity theo-ry ,the coding with Matlab is completed and the deformable model is established .Combined with the project observation da-ta ,the corresponding parameters are calculated and this prediction theory is inspected .The results show that the predicted values are close to the actual ones and the relative error is within 4% ,which provides the basis for landslide forecast warn-ing and safety production .
