Abstract

Basic research of lateral earth pressure based on physical and numerical experiments began in 1998 at the institute of the author and it has continued to the present time. The physical research should prove the behavior of ideally non-cohesive granular mass during three basic types of structure/wall movement towards in active and passive directions. The first research period in 1998-2000 was aimed on active pressure, and in 2001-2002 on the first long-term experiment with passive pressure (E3/0.2). Then new experimental equipment was developed between 2003 and 2009 on a contemporary advanced level. The first long-term experiment with passive pressure E3/0,2 acting on a wall rotated about the top was repeated and as double same long-term experiments, denoted as experiments E5/0,2 (2010) and E6/0,2 (2011). The new equipment is completely under computer control and it has five bi-component pressure sensors in the arbitrarily moved front wall and six sensors in the solid back wall. The velocity of the front wall movement can be arbitrarily slow from of 3.684 to of >0 mm/min, the maximal pushing force being about of 2870 kN. The maximal recording frequency is of 1000 Hz and it can accommodate a huge quantity of data of 803 MB/day. The paper presents proof that theoretically considered passive pressure of ideally non-cohesive material on a wall rotated about the top cannot be achieved.

Double Case of Passive Pressure Acting on Wall Rotated About the Top

Chicago, Illinois

Basic research of lateral earth pressure based on physical and numerical experiments began in 1998 at the institute of the author and it has continued to the present time. The physical research should prove the behavior of ideally non-cohesive granular mass during three basic types of structure/wall movement towards in active and passive directions. The first research period in 1998-2000 was aimed on active pressure, and in 2001-2002 on the first long-term experiment with passive pressure (E3/0.2). Then new experimental equipment was developed between 2003 and 2009 on a contemporary advanced level. The first long-term experiment with passive pressure E3/0,2 acting on a wall rotated about the top was repeated and as double same long-term experiments, denoted as experiments E5/0,2 (2010) and E6/0,2 (2011). The new equipment is completely under computer control and it has five bi-component pressure sensors in the arbitrarily moved front wall and six sensors in the solid back wall. The velocity of the front wall movement can be arbitrarily slow from of 3.684 to of >0 mm/min, the maximal pushing force being about of 2870 kN. The maximal recording frequency is of 1000 Hz and it can accommodate a huge quantity of data of 803 MB/day.
