Abstract Research purposes: The characteristics, content and key points of the engineering geological investigation supervision in passenger dedicated railway line construction are summarized, which can be used for reference in the similar engineering in the future.
Research methods: Combining the work of engineering geological investigation supervision in Wuhan-Guangzhou passenger dedicated railway line, such supervising methods as patrolling in-situ, sampling test and standing aside， adopted, the content, key points and quality control measures in railway geological investigation supervision are analyzed and summarized.
Research results: Key points and principles to control the quality of passenger dedicated railway line geological investigation supervision are put forward, effective work methods，proposed.
Research conclusions: The key point of the work is set on the quality control of geological investigation in situ. The principles such as inspecting and guiding in situ, strict management of geological investigation quality, and regular examination of laboratory，persisted in. Management in situ, testing and sampling, report censoring during the process of investigation are controlled as key points.
