Abstract:

Some improvements are made based on the Hilf method. The pore air pressure and pore water pressure can be calculated regarding the pore air pressure and pore water pressure as independent variables. The analysis method of stability on the strengthen of embankment with clotty is given when the pore air pressure and pore water pressure are all taken into account. The results show that the stability coefficient increases with the enhance of matric suction; and once the pore air pressure is ignored, the stability coefficient a little bigger than it is in fact. The pore air pressure has no influence on the resistance of shearing. when is equal to ; and the calculated stability coefficient is the same. Not only the pore air pressure and pore water pressure must be taken into account; but also the adding of clotty of ground is considered when the stability of embankment is analyzed during the construction period.

Key words: pore air pressure, pore water pressure, breakwater embankment, stability
