The geological phenomena of the long distance water diversion project in Xinjiang are very abundant and complicated. In different areas

the engineering geological phenomena and geological bodies have unique quality and character. In order to satisfy the requirement of project construction

thoroughgoing and painstaking investigation of geological phenomena is necessary. Beside the normal geological problems in the water diversion works of south bank of the Wulonggu River

such as soft rock tunnel

soft foundation under the dam of “500” reservoir and desert sand of the aqueduct have been investigated; and the huge water diversion works system has been constructed and running well now. However

the other problems need to be studied and confirmed further in the future running of this system.
