What is effective overburden pressure?
What is effective overburden pressure? When the soil is subjected to some load, it transfers the load to water in the pores and soil grains. This is defined as effective overburden pressure and otherwise will be called as inter-granular stress or effective stress. It increases with increasing depth of soil. What is Geostatic pressure? 1.
