| 摘 要： | INTRODUCTIONLandslides annually cause a great amount of cas-ualties withinthe Chinese population and great lossesin the Chinese economy . The number of casualtiesreached 232 killed and 2 missing people in 2003 and283 killed and 69 missing people in 2004 . The eco-nomic losses amount to a total of 730 billion US $in2003 and 475 billion US $in 2004 (Zanetti ,2005 ,2004) .The DAAD (German Academic Exchange Serv-ice) is financing a project to investigate landslides .The project is a coo…

| Abstract: | To enhance the general knowledge of landslides in China, the DAAD (German Academic mapped to gather information concerning landslides and their correlation to lithology, slope angles and texture. The geological mapping contained the characterization of the lithologicai units. The characterization of the shape of landslides and the classification of rocks into units with similar geotechnical behavior is contained in the geotechnical map. Samples were taken and investigated using X-ray diffraction to identify the clay minerals and geotechnical tests to determine the effective shear angle and cohesion of rocks and soils. Geotechnical mapping showed a close connection between lithology, slope angle and texture concerning the occurrence of landslides. Most landslides occur on the northern bank of the Qingjiang River where the dip angle of the bedding is nearly parallel to the slope, resulting in potential and effective slide planes. On the southern bank only sporadic and small landslides occur because the bedding is antipodal to the slope angle. This pilot work is a base for further and more detailed investigations in this area. |
