REVICE MECHANISM AND DEVELOPING TENDENCY OF ANCIENT LANDSLIDE IN TUFENOYAN-MAJIABA OF THREE GORGES REGION
Following Jifazi landslide occurred in 1982 and Xintian landslide in 1985
a catastrophic landslide of Majiaba in Zigui County occurred on 16 July
1986
about 7.5 km south of Yangtze River
being a complete revice of historic dormant landslide. Its revice was triggered by particularly heavy rainfall. The reactivated landslide attained a volume of 30 million m~3. Being due to damming gully by rock collapse at upper part of the slope
impounding water level in the gully rose rapidly
flooding emptied both-sidely into ancient slide deposits in a short time
creating a strong dynamic-statical water pressure
pushing ancient slide deposits on the middle-lower part of the slope to move downward till the valley. The gravity center of the gliding mass is higher now
there are many ruptures on the ground
both sides natural drains are filled by sliding deposits
therefore there must be a tendency of damming river. Taking continually monitor of slide movement
sliding
warning repairing drain system
transforming paddy fields into dry land
ramming ruptures on the ground can be taken as countermeasures.
