-
-
Abstract
The data of engineering geological and geophysical survey indicate that the geo-hazards in the Hangzhou Bay can be divided into two categories,namely active and restrictive geo-hazards.In the paper,we studied the types,distribution pattern and formation mechanism of the hazards and their risk to marine engineering programs,with focus on tidal channels,ancient river channels,soft soil,seabed landslide,sand liquefaction and shallow gas in order to provide useful basic information for offshore development and construction in this area.
