摘要
岩质边坡稳定分析是工程地质勘察设计中的一项重要工作,主要包括岩体结构面产状量测、优势结构面统计、结构面稳定性分析以及报告编写等四部分内容。目前存在如下问题:一是岩体结构面量测一般采用传统的人工现场量测法,存在工作效率较低、量测范围受地形限制、结构面数据代表性较差的问题;随着边坡高度增大,坡度增陡,还存在严重的安全风险问题;二是结构面统计和结构面稳定分析虽然有单独的软件,需要人工转换才能完成上述两项工作,存在效率较低,无法批量分析和易出错问题;三是目前尚未出现能够一站式完成上述全部工作的软件,更无法自动生成分析报告。针对上述问题,作者应用Excel—DNA技术开发了岩体结构面一站式分析软件,包括利用三维实景模型进行结构面产状计算,结构面统计、结构面分析和报告编制等功能。经过与传统分析方法对比,成果正确,精度可靠。利用软件可有效提升勘察设计工作的标准化水平,促进生产效率和成果质量的大幅提升,具有很好的实用价值。
The analysis of rock slope stability is an important task in engineering geological exploration and design,which mainly includes four parts:the measurement of the occurrence of rock mass discontinuities,the statistics of dominant discontinuities,the analysis of disconti⁃nuities stability and the compilation of report.At present,there are the following problems:first,the traditional artificial field measurement method is generally adopted for rock discontinuities measurement,which has the problems of low efficiency,limitation of terrain to measure⁃ment range and poor representativeness of discontinuous data.Second,although there is a separate software for discontinuity statistics and discontinuity stability analysis,manual conversion is needed to complete the above two work,which has low efficiency,cannot be analyzed in batches and can make mistakes easily.Third,there is no one-stop software to complete all the above work,let alone automatic generation of analysis reports.To solve above problems,the paper uses Excel-DNA technology to develop a one-stop analysis software for rock disconti⁃nuities.This software includes using 3D real model to calculate discontinuance occurrence,discontinuance statistics,discontinuance analy⁃sis and report preparation and other functions.Compared with the traditional analysis method,the results are correct and their accuracy is re⁃liable.Using software can effectively improve the standardization level of exploration and design,greatly promote the production efficiency and the quality of results,and has good practical value.
