摘要

Statigraphic sequence of Jinggangshan Hydropower dam foundation is Cretaceous red bed. Rocks are mostly argillaceous siltstone,silty mudstonek have low bearing capacity, uneven deformation. Water loss of weak rock is easy to dry. Its strength and resistance of deformation rapidly decreases within a short period of time. Disposal measure suggestions are proposed based on preliminary study of weak rock characteristics.
