Ill. Admin. Code tit. 35, § 811.304 - Foundation and Mass Stability Analysis
a) The material beneath the unit shall have
sufficient strength to support the weight of the unit during all phases of
construction and operation. The loads and loading rate shall not cause or
contribute to the failure of the liner leachate collection system.
b) The total settlement or swell of the
foundation shall not cause or contribute to the failure of the liner leachate
collection system.
c) The solid
waste disposal unit shall be designed to achieve a safety factor against
bearing capacity failure of at least: 2.0 under static conditions and 1.5 under
seismic loadings.
d) The waste
disposal unit shall be designed to achieve a factor of safety against slope
failure of at least: 1.5 for static conditions and 1.3 under seismic
conditions.
e) In calculating
factors of safety, both long term (over hundreds of years) and short term (over
the design period of the facility) conditions expected at the facility shall be
considered.
f) The potential for
earthquake or blast induced liquefaction, and its effect on the stability and
integrity of the unit shall be considered and taken into account in the design.
The potential for landslides or earthquake induced liquefaction outside the
unit shall be considered if such events could affect the unit.
