中文摘要：
通过教．值模拟计算得到隧道前方富水溶洞和含水断层的瞬变电磁响应，以正演计算模型参数及响应为专家样本，以VB为开发工具，开发出数据库反演专家系统。以Matlab为开发平台，编程建立了神经网络专家系统。将LSSVM函数加载到Matlab中，编程实现了LSSVM专家系统。3种专家系统在实际工程中的应用表明：瞬变电磁法探测隧道前方含水异常体地电结构时，采用专家系统进行反演，反演精度是能够满足工程需要的。
英文摘要：
Database inversion expert system is developed by using VB as the development tool, and using forward calculation parameters and transient electromagnetic responses, which for water-rich Karst cave and hydrous fault in front of a tunnel is obtained through numeric simulation calculation, as expert samples. On the development platform of Matlab, neural network expert system is established through programming. Load LSSVM function into Matlab to realize LSSVM expert system＇through programming. Application of the 3 expert systems in actual projects indicates When transient electromagnetic method is used to probe geoelectric structures of water-rich abnormality in front of a tunnel, the accuracy of inversion by the expert system is sufficient for the requirements of a project.
