包裹体方法在工程勘察中的应用

Application of inclusions method in engineering survey

在工程勘察中一般采用传统的地质分析法来判定断层的发育情况和活动性，但在许多情况下却难以作出准确的判断。我们在一些工程的地基勘察及稳定性评价中引入了地球化学方法，即通过矿物包裹体的类型、大小、形状和分布情况以及均一化温度等特征研究，结合显微构造分析，判定断层的规模、切割深度、相互切割关系及活动性等特性，取得了较满意的结果。

Geological analysis method is generally used for determining development and activity of faults in engineering survey, but it is not accurate in some cases. We have applied a method of inclusions in combination with microstructure analysis to judge the scope, depth, cut relation and activity of faults and got effective and characteristic results in the survey and foundation stability evaluation of some projects.
