文章简明扼要地介绍了赤平极射投影的作、读图法,并以楔本滑坡稳定分析为例进一步阐明其分析步骤,指出这种方法不仅分析过程较简便,而且分析结果的精度足以满足工程之需,在解决空间问题时较解析法为佳。最后提出了在运用此法过程中应注意的有关事项。 The article briefly introduced the mapping and mapping methods of polar projections of the polar plane, and further explained the analysis steps using the wedge-landing stability analysis as an example. It was pointed out that this method not only made the analysis process easier, but also the accuracy of the analysis results was sufficient to satisfy the project. The need is better than the analytical method when solving space problems. Finally, related issues that should be noted in the process of applying this method are proposed.
