摘要
地质调绘法在工程实践中一直缺乏系统的理论指导。以隧道区域内断层为预报目标,根据断层的基本特征和规律,总结归纳了一套以地面复查为基础,地质编录为核心,工程地质评价为深化的断层地质调绘分析方法。以厦门天马山隧道为例,详细介绍了断层地质调绘法的具体实施过程和适用范围,阐述了其在超前地质预报过程中的意义。通过预报结果与实际结果对比,预报效果良好,充分验证了地质调绘法预报断层的可行性及准确性。
In engineering practice,geological investigation always lacks of systematic theoretical guidance.According to the basic characteristics and principles of faults,a set of fault geological investigation method was summarized to forecast faults in tunnel areas.This set of method involves ground review,geological information documantation and engineering geology assessment in tunnel construction.Using the Tianmashan Tunnel in Xiamen as an example,the specific operation process and the application scope of fault geological investigation is introduced in details.Its significance in geological forecast is highlighted.Comparison of the forecast with actual result shows that the forecast result was acceptable,which justified the feasibility and the accuracy of geological investigation in fault forecast.
