Development and research on computer-aided system of landslide engineering assessment and design

From the view of integration of the stability assessment and control design of landslide engineering,the paper constructed the total structure of the computer-aided system of slope engineering integration design,elabo-rated the design method and main functions of computer-aided system of the pre-processing module,the core cal-culation module,as well as the post-processing module.Based on this,and visualized programming language Vis-ual Basic for the foundation,and using CAD secondary development as the platform for graphics output and Excel as databases with component technology,the computer-aided system of landslide engineering information design was developed.The software system is characterized by constructing geological model of slope interactively,analysis and calculation intelligently,and drawing section and structural plans automatically,while the parameter inversion,stability calculation,sensitivity analysis and thrust calculation of landslide and slope excavation design,anti-sliding-block,anchor,drainage works and slope protection design are provided,they enriched the content of the slope design and widened its application scope,the integration,informatization and intelligence of slope engi-neering stability assessment and control design are realized.Finally,taking some landslide integration design in Tongliang County of Chongqing City for example,the system feasibility and reliability were confirmed.
