Research On Compositive Reconnaissance Means And Technology About Spherical Weathering Granite In Shaoguan-Huadu Sect Of Wuhan-Guangzhou Special Passenger Transport Railway

The phenomenon of grantic spherical weathering is frequently encountered in railway engineering which traverses granite areas. Limited to various factors, correlative research is few.So the author will do some research in this article.This research will be done in Shaoguan-Huadu sect of Wuhan-Huadu special passenger transport railway, by three means which includes exploration drilling , geophysical prospecting and in situ test . About the exploration drilling , the non-pump reverse cycle technology and the double drilling technology with double piples are emphatically used. About the geophysical prospecting,three means are emphatically used. About in situ test, four means are emphatically used. Finally, one compositive reconnaissance means is found .
