摘要： 在工程勘察设计生产实践中，工法勘察对岩土工程勘察具有重要意义。结合某公路TMB掘进隧道、某公路下穿铁路顶进框架桥的工程地质勘察实例，从工法勘察角度出发，介绍了硬质岩石公路TMB掘进隧道、软土地区下穿铁路顶进框架桥地质勘察一般工作方法。通过具体工程勘察实例，分析探讨了工法勘察在公路工程地质勘察应用中的特点，提出了工法勘察重要内容。工程实践表明，随着公路工程建设中施工技术革新，公路地质勘察过程中的工法勘察意义更加明显，对于具体工程项目开展专门的工法勘察就显得尤为重要了。

Abstract: The geotechnical investigation for the special construction methods is an important part of the geotechnical engineering practice. This paper presents two case histories of geotechnical investigations for a highway tunnel to be excavated by the Tunnel Boring Machine (TBM) method and a proposed highway box culvert under cross a railway by horizontal jacking method. The geotechnical investigation aspects of TBM excavation in hard rock and horizontal jacking of highway box culvert in soft soil are introduced in the paper. The characteristics of the geotechnical investigation for the special construction methods are evaluated. The engineering practices indicate that in the highway construction projects, the special investigation has wide applications and is also important.

Key words: geotechnical investigation for the special construction methods, geotechnical investigation for highway project, tunnel boring machine excavation method, highway box culvert jacking
