Failure of fill slope in embankments:
It is also known as slope stability. The factors which are the cause of the failure of the fill slope are as follow:
- We often encounter the problem of the over stressing of the foundation soil. The main cause of this problem is the presence of the soft cohesion soil during the construction or immediately after the construction. It is often observed that the short term stability of the fill slope on soft cohesive is more critical than the long term stability of the cohesion soil. This is because, with the passage of time due to pore pressure dissipation the foundation is further strengthened.
- The main factors causing the failure of the earth dams are draw down and piping.
- Failure may be due to the presence of dynamic forces like earth quake, blasting and pile driving, and many other factors vibrational waves for a near by construction site.
Structural integrity of fill slopes is dependent upon the maintenance of specifications over time. Any factor or factors which compromise those specifications can lead to failure. This is “unrealistic” as a practical matter, but failures of fill slopes is far too common for discussion of the relevant phenomena to be avoided.
