The three stages in the development of the geological
surveying technologies for railway tunnels, i.e.〖KG-*3〗, the start stage, the development stage, and the technical
breakthrough and innovation stage, are briefly reviewed.The stateofart of the geological surveying
technologies for railway tunnels, such as the remote sensing technology, the
geological mapping technology, the geophysical prospecting technology, the
drilling exploration technology, the insitu testing
technology, the geotechnical testing technology, the advance geological
prediction technology, and the comprehensive geological surveying
technology,are analyzed.The challenges in the geological surveying technologies
for deep railway tunnels in mountainous areas with complex geological
conditions, ultralong railway tunnels crossing
underneath deep sea water, highspeed railway tunnels,
and railway tunnels with special construction methods are analyzed according to
the requirements of the tunnel construction and the level of the geological
surveying technologies. In consideration of the current scientific and
technological level and the future development trend, the prospects of the
geological surveying technologies for railway tunnels in terms of the surveying
methods and equipment, the digital insitu testing
technology for deep rock mass, the advance geological prediction technology,
the informatized and intelligent geological surveying technologies for railway
tunnels are put forward. It is considered that the geological surveying
technologies for tunnels will develop toward the direction of wider area,
higher efficiency, more accurate, and more intelligent, and will make greater
breakthroughs.
