Abstract

See full text

A method of maintaining structural integrity of a subsiding earthen fluid containment structure is disclosed and comprises forming a lined containment infrastructure (100) including a convex bulged crown portion (120), floor portion (110) and sidewall portions (115) which enclose a comminuted earthen material (126) within an enclosed volume (125) such that fluid flow from the lined containment compound is restricted. The bulged crown flattens, thickens and diminishes in surface area during subsidence of the comminuted earthen material as fluid is removed. The bulged crown is shaped to avoid tensile stresses which may otherwise result in breach or failure of lined containment during subsidence. Further, the lined containment structure can include an inner insulative layer and an outer impermeable seal layer having unique contributions as described in more detail herein.
