基于智能手机的岩质边坡快速分析方法

Smart Phone-based Method of Rapid Rock Slope Stability Analysis

针对岩质边坡稳定性分析缺乏现场快速分析方法的问题,提出了一种基于智能手机进行分析的方法。首先回顾了赤平投影的原理和使用赤平投影进行岩质边坡稳定性分析的方法,然后阐述了如何利用智能手机进行产状测量、组织边坡产状数据以及进行边坡稳定性分析,最后对岩质边坡稳定性快速分析软件进行了测试。结果表明,使用该软件可以快速获取结构面产状、自动绘制赤平投影图和给出稳定性分析结论,在现场就能够快速区分出稳定与潜在不稳定的边坡,以便有针对性地进行详细调查工作。总的来说,使用手机进行岩质边坡稳定性分析,可以减少工作量,提高工作效率,具有一定的推广价值。

This paper proposed an analysis method based on smart phone to suave the problem rock slope stability analysis in the field. Firstly, the paper reviews the principle of stereographic projection, and the use of the stereographic projection in analysing the stability of rock slope. Then, it introduces a way to measure the occurrence of structural plane by using a smart phone, the organization and display of the oc- currences data, and the process of stability analysis. Finally, the software is tested for the rapid rock slope stability analysis. The results show that, this software can obtain the occurrences of structural plane rap- idly, draw the stereographic projection and produce the conclusion of stability analysis automatically. With this software, geologists can distinguish potentially unstable slopes from stable slopes in the field so as to perform detailed targeted investigations. In general, the smart phone method is quite applicable field work for it can analyze the stability of rock slope, reduce the workload and increase the work efficiency.
