摘要:

为减少地铁隧道施工中经常出现的围岩坍塌、透水等地质灾害,分析施工段围岩地质情况,采用一种基于权重的岩体基本质量亚级分级方法对围岩进行分级,结合C#与ArcEngine的二次开发,根据距离高次方反比法原理,利用已有地质钻孔数据,设计出对围岩进行等级估算和三维分级显示渲染功能的系统,并对该亚级分级方法的准确性进行验证。实验结果表明,基于权重的岩体基本质量亚级分级方法对隧道围岩分级更精确,具有较好的实用性。设计的系统对围岩等级估算的反算误差为8.82%,与实际国岩开挖后测得的信息对比误差为13%,三维分级渲染结果与实际情况较为接近,该方法可以为地铁隧道施工提供参考。

Abstract:

In order to reduce the surrounding rock collapse,flooding and other geological disasters that often happen in subway tunnel construction and to get a clearer understanding about the geological conditions of the surrounding rock in the construction area,this paper adopts a basic quality sub grade of rock mass method based on the weight to classify the surrounding rock,combining C# with the secondary development of ArcEngine to design a system according to the principle of Inverse Distance Weighted(IDW) to estimate the grade and realize the 3D hierarchical display and rendering of the surrounding rock based on the existing drilling data.At the same time,this system can be used to verify the accuracy of the sub grade method.Experimental results indicate that the basic quality sub grade of surrounding rock method based on the weight is more precisely in the classification of tunnel surrounding rock and has better practicability.The inverse error of system estimation in the classification of the surrounding rock is 8.82%,compared with the excavation revealed information,the difference is 13%,the 3D hierarchical display and rendering of the surrounding rock is closer to the actual situation,which can provide a reference for the subway tunnel construction.

Key words: subway tunnel, surrounding rock sub grade, C# technology, ArcEngine secondary development, Inverse Distance Weighted(IDW) interpolation, 3D visualization
